---- NATALIE NEFF Published Date: 1/10/05
Pontiac likes to lay claim to the title of original muscle car with its GTO, and while that first 1964 model was more a big-engined Tempest than a pure Goat, we're hardly one to quibble over the finer points. What is definitive to our minds, however, is this: It would be at least a year before the diminutive Ford Mustang, which bowed that same year, would even come close to the midsize Pontiac's performance, and at least four years before a Mustang had any chance of out-and-out beating one. That first year, however, was no contest.
In its top-end form, a stock '64 GTO with a 348-hp (at the flywheel), 389-cid V8 was good for 6.6 seconds to 60 mph and under-15 in the quarter-mile. Not until the GT350 debuted the following year would a Mustang get close, and even then it still fell shy of the Pontiac-by then up to 360 horses-by nearly three-quarters of a second.
Yet today when we think of muscle cars, it's the Mustang's paradigm that persists, that of the pony car, the little car with the big heart. The intermediate has long since disappeared, a point driven further by the fact that today the GTO is not even two inches longer than a Mustang GT.
So as we approach three years without a Chevrolet Camaro to throw down with the Mustang GT, we thought it would be fun to pit the Pontiac against the de facto reigning pony car champ, to see which has more of what it takes to gallop home the winner.
The GTO may wear the Pontiac shield, but as we all know by now, behind that kidney-shaped grille breathes an Aussie beast. No worries; its V8-powered, rear-drive, two-door design gives it all the street cred we require for a legitimate showdown with the best out of Dearborn.
When last we visited with the GTO, the brute from Down Under was pounding out a dust cloud raising 350 horses and 365 lb-ft of torque, grunting and growling and sounding every bit the frightening Detroit iron its fabled name recalls. In its 2004 form the GTO was good for 5.49 seconds to 60 mph and a quarter-mile time of 13.82 seconds at 103.0 mph. Not bad numbers, to be sure, especially given the GTO's none-too-buoyant 3700-plus-pound curb weight, though we're sure the old model could have dropped a couple of tenths if not for the crazy amount of wheel hop it kicked up at the line. The way the Mustang sounds, feels and drives- from the ample grunt under the hood to the exhaust rumble to the clearly improved suspension and steering response-has made for many a happy staffer around One AutoWeek Tower.
Today the ol' Goat has traded in its 5.7-liter LS1 V8 for the monster 6.0-liter LS2, complete with 400 hp and 400 lb-ft of torque all routed through either a four-speed automatic or, more in line with our purposes, an optional six-speed manual. Add to that a more obvious performance-oriented look, including a more aggressive rear fascia with twin tailpipes, bigger brakes with red calipers and a new hood with functioning dual hood scoops, and there is plenty of new stuff going on with the 2005 GTO.
Same goes for the Mustang. After 25 years of Fox-bodied cars, with little of substance changing from one model year to the next, the folks at Ford have finally given us an all-new Mustang with which to play.
The last Mustang GT we tested in 1999 turned out 260 hp from its 4.6-liter two-valve V8. On the track that translated into 5.88 seconds to 60 mph, with the quarter-mile passing in 14.44 seconds at 96.9 mph. Of course, the much more powerful SVT Mustang Cobra we ran through our AutoFile tests in 2003 blew that away with a 4.85-second 0-to-60-mph time, but the new Cobra has yet to come out, so we'll hold onto those figures for now.
>From the moment you slide behind the wheel, crank that awesome small-block and fling it into a corner, you know this GTO shares little with its namesake other than you can have a bunch of fun behind the wheel.
The new Mustang comes in two distinct flavors. The base model, a lively six-cylinder churning out 210 horses and 240 lb-ft of torque, makes up the bulk of Ford's pony car sales, a full 70 percent. It uses a newly designed 4.0-liter engine with overhead cams in place of the aging 3.8-liter ohv V6 that made its home for so long underhood. For our purposes, we turned to the backstraight-blazing, V8-powered GT, with 300 horses' worth of thoroughbred top-end married to 320 lb-ft of clomping off-the-line grunt. It depends on a highly revised version of the 4.6-liter, using three-valve heads now as well as variable-valve timing.
Our first few experiences with the Mustang GT have proven Ford still knows a thing or two about building a fun car, despite the blahness the Five Hundred imparts. The way the Mustang sounds, feels and drives-from the ample grunt under the hood to the exhaust rumble to the clearly improved suspension and steering response-has made for many a happy staffer around One AutoWeek Tower.
Of course, our first time behind the wheel of a GTO more than a year ago proved more than fun, too. We thought the steering felt fine, calling it "quick, crisp and responsive." We especially enjoyed how well the vehicle handled, its "chassis almost unflappable over road imperfections and through aggressively driven curves," its "superior body control... particularly fine when hustled full-on through tighter combinations of turns." We loved the notchiness of the six-speed, and found the interior design fresh and exciting. The skin? Well, we had nothing bad to say about it; we simply called it forgettable.
Bringing the more-powerful-for-2005 model to the track opened some eyes, to say the least. All the straight-line numbers hit right where we had expected-5.15 seconds to 60 mph, 13.75 seconds in the quarter-mile at 104.1 mph, trumping the Mustang's numbers across the board-but the GTO didn't feel nearly as lively or as sharp as we had remembered. The reason? Driving the car back-to-back with the new Mustang GT.
The difference was most marked through the slalom course. The GTO's steering, while fine on its own, felt hugely lumbering and slow compared to the Mustang's. The Pontiac's handling style required us to predict each cone by turning the wheel early, then waiting half a heartbeat for the car to follow behind. Doing so made the car a breeze to drive, as it could basically be steered on the throttle like that all day long. Problem was, switching to the Ford almost always resulted in a spinout the first go-through the cones because our hands would instinctively try turning in early, only to have the car react in a flash and loop. In other words, where the GTO's steering wheel-and everything it's connected to-felt heavy, muddy, even numb, the Mustang's had a sharp, immediate turn-in feel and bristled with visceral sensations of the road at every turn.
The Mustang felt sharp throughout the test. Down the drag strip the shifter made for quicker, more precise shifts than the GTO's, even if it ultimately couldn't match the extra 100 horses the Pontiac's increased displacement affords. The Mustang's brakes felt better, too, even though both cars required 128 feet to stop from 60 mph. After several deceleration runs the GTO's brakes started to shimmy on application, indicating a warp or other negative wear pattern; the Mustang's felt fine.
Overall, the difference with the Mustang mechanicals was you could actually feel what they were doing; the GTO, in the immortal words of one staffer, felt like it was wearing an auto-condom. A good set of performance tires could put the Mustang into another league altogether.
As for style, the Ford looks cooler, inside and out, and cool counts in this segment. Sure, the Mustang takes zero styling risks as it is practically a carbon copy of the '67 fastback, but the '67 was a cool-looking car. The GTO, on the other hand, is total blandsville. It leaves absolutely no impression whatsoever.
Then there's the matter of the moolah. The pony car segment has traditionally been a good one in terms of bang-for-buck deals. In that regard, the 2005 Mustang GT is a hard-core traditionalist, making for one heckuva compelling package when you consider it costs thousands of dollars less than the Pontiac.
For our tastes, in the end, pure might doesn't necessarily prove right. For all the GTO's brute power-its liter-and-a-half, 100-horse advantage, its quarter-second-quicker 0-to-60-mph time, three-tenths- quicker quarter-mile time-not to mention the car's hefty price premium, it simply cannot match the Mustang for feel, style or value.
Overall, the Mustang backs up its looks with a handling performance that puts to shame the GTO's. Any minor shortfall at the strip was worth how brightly the Mustang took on the cones. Sound the bell, it's no contest: The winner is the Mustang GT.

one80out@hotmail.com - 16 Apr 2005 05:08 GMT I'm confused. First, where's the '05 Stang's quarter mile time? All I see is that the '05 GTO was "three-tenths-quicker" than the Stang, and that the '05 GTO turned in a 13.75 @ 104.1. Second, it says the 20 ci smaller, 50 hp weaker '04 ran a 13.82 @ 103.0. 50 hp is worth only 1 mph? 100 hp more than the Mustang is worth only 7 tenths? There's something wrong with both numbers.
Anyway, I don't know the source of this article, but I say anyone who prefers a 300 hp 281 to a 400 hp 364 is nuts. This "value" thing -- give it a rest. I just can't believe the apathy of all the old school gearheads for a 400 hp car. Hemi Cudas, that wish they actually put out 400 hp, are going for six figures all day long. I mean, if that's the value of a 400 hp bone stock car in today's marketplace, then it's the GTO that is an incredible bargain. And with a few mods, a little boost, forget about it.

This "value" thing -- In the same car ? sure. in a different car it's a whole different story and that's what the article is all about. It shows that the mustang, even though it has less power, will kick the GTO's a.s in a road race. On the drag-strip, sure, it's all about power and how it's planted to the pavement (which the mustang is better at, solid axle !)

All I > see is that the '05 GTO was "three-tenths-quicker" than the Stang, and [quoted text clipped - 13 lines] > > 180 Out The article lets you do the math for yourself. The GTO with 1.4more liters and 100 more hp was 0-60 in 5.15sec, 13.75sec 1/4mile. The Stang was .25 slower 0-60 that is 5.4. The Stang was also three tenths slower 1/4 mile henceforth 14.05. As far as the GTO being slightly quicker then the previous year perhaps the larger 6L motor is heavier then the previous 5.7 or maybe they had to change gearing or something else that gobbled up the extra 50hp. Again with 100 hp more then the Stang it is only .3 seconds quicker then the Stang not 7 tenths not sure were that came from. Remember the Mustang weighs much less then the GTO (over 200lbs less) and speed is based on more factors then hp and weight such as gearing for instance. Source of article. It mentions around the One Autoweek Tower so I imagine this is an Autoweek article. :) Now other factors to consider that make one choose a car with less hp over another. First off it clearly indicated that the GTO is an Aussie made car the Mustang American, asking an American consumer that means a whole lot. Right now you are basing your decision on a hp or cubes for that matter. How about handling, breaking, price, style? Also aftermarket accessories. The potential of the Mustang alone is worth more then shoving a 6L into a car that looks like a Pontiac Sunbird.
Oh keep in mind the '04 Cobra had whopping better times then the GTO with a 0-60 of 4.85sec 1/4 mile while not listed have been noted well in the 12's. I would imagine the GTO is more lined up for a Cobra rather then a GT.

'05 GTO: wt: 3787; gear: 3.46:1; '04 GTO: wt: 3821; gear: 3.46:1. So the gear is the same and the weight is less (although a mere 34 lb diff may be accounted for by the weight of gas, the test driver, etc.)
These numbers are from the side by side test of '05 GTO vs. '05 Mustang in January '05 Car and Driver http://www.caranddriver.com/article.asp?section_id=15&article_id=8908&page_number=1 and the December 2003 test of the '04 GTO http://www.caranddriver.com/article.asp?section_id=3&article_id=7360&page_number=1 . C&
C&D also got a 5 mph trap speed improvement from the additional 50 '05 horses, and the '045 was 0.7 seconds quicker in the quarter. These numbers make sense. The Autoweek numbers don't.
Here are all the vital stats from the C&D stories:
'04 GTO:
0-60: 5.3. 1/4 mile: 14.0 @ 102; 346 ci; 350 hp @ 5200; 365 lb-ft @ 4000; wt: 3821; gear: 3.46:1
'05 GTO:
0-60: 4.8; 1/4 mile: 13.1 @ 107; 364 ci; 400 hp @ 6600; 400 lb-ft @ 4400; wt: 3787; gear: 3.46:1
'05 Mustang GT:
0-60: 4.8; 1/4 mile: 13.8 @ 103; 281 ci; 300 hp @ 5750; 320 lb-ft @ 4500; wt: 3575; gear: 3.55:1
> Again with 100 hp more then the Stang it is only > .3 seconds quicker then the Stang not 7 tenths > not sure were that came from. I got my wires crossed between Autoweek's numbers showing the '05 GTO being seven tenths quicker than the '04 GTO, and three tenths quicker than the '05 Stang. I meant to type "3" but it came out "7". For the GTO to beat the Stang by seven tenths would be OK (e.g., see the C&D numbers); three tenths from a car that's only 200 lbs heavier and 100 hp stronger and I say something's wrong.
> How about handling, breaking, price, > style? Handling and braking: From the C&D comparo:
'05 GTO: wt ft/r %: 53.8/46.2; strut, coils, sway bar; IRS, coils, sway bar; 300 ft skid pad g: .88; vented discs/vented discs; 70-0: 167 ft; '05 Stang: wt ft/r %: 52.5/47.5; strut, coils, sway bar; IRS, coils, sway bar; 300 ft skid pad g: .89; vented discs/solid discs; 70-0: 170 ft.
> Also aftermarket accessories. Potential for mods is where the GTO leaves the Stand far in the dust. First, it comes with IRS and an utterly bullet-proof 6-spd, while the Stang comes with a solid axle that will NEVER equal IRS in street handling, and the latest update of the failure-prone T-5. So the same aftermarket handling improvements to both will still leave the Stang behind.
And as far as the engines, well that was my point to begin with, that a 364 ci LS2 (that means with the GOOD LS6-style heads and the ability to pop it out to 400+ ci no problem) kills the GT mod motor off the assembly line, and with a few mods will kill the GT, the Cobra, AND the GT500 too. There is no replacement for displacement. Already there's a Vortech blower/intercooler kit for the '04 GTO http://www.vortechsuperchargers.com/products/yourcar/04_gto.html : 481 hp and 435 lb-ft @ 7-8 psi. That's with a stock baseline of 350 hp, 365 lb-ft. Adding the same percentage increases to an '05 puts you at 550 hp, 477 lb-ft.
Finally, as far as "value," the '05 GTO is already selling at or below list price. The '05 Stang is barely there. With added dealer profit of $5000+ the Stang GT verts are going for thousands MORE than the GTO. There's also the collectibility factor. I predict the GTO will be the Hemi Cuda of 2030, and the '05 Stang will be the '65 with the 289-2v. As in $1 mil for a perfect low miler, vs. $20,000. Remember, no one bought the Hemis when they were new either.

The GTO is more in line with the Cobra or so it should be. If there was a retro Lemans this would be more suitable to compare with the run of the mill Mustang/ GT. Here we can see both cars IRS with 6 speeds too. The Cobra out handled and performed the GTO '04 when they were both produced. There are many comparisons that were done in '04 with the GTO Cobra. For instance: http://www.roadandtrack.com/article.asp?section_id=31&article_id=1368&page_number=5 Wait till the Cobra makes its come back by the end of the year to have a fairer comparison although IMO the regular GT does a hell of a job!
Motortrend has an interesting article on the GTO of '04 mentioning the Cobra as well. http://motortrend.com/roadtests/coupe/112_0312_gto/index.html If you go on over all car the fox platform with its 25 year old chassis really was needing a replacement. The performance stats in a fair comparison was Cobra 0-60 4.8 13.0 1/4mile @ 110.7 mph to GTO 0-60 5.3 13.62 1/4 mile @ 104.78 mph.
Motortrend also list the '05 Stang as 0-60 5.1 1/4 mile 13.6. http://www.lonestarstangs.com/homepage/page8.jpg Not bad for 100 less hp and if you went to look for sticker prices you could easily afford an aftermarket Supercharger to play catch up. MSRP for a Premium GT is $26,125. GTO is $32.295. Compliments of http://autos.yahoo.com/.
I have to disagree with your presumption of this very new motor having a huge aftermarket parts source. It even took the 4.6 a bit of time to catch on with production figures probably 10 times greater then the GTO or Vette possibly combined. You mention little mods making it go better then the Stang. The introduction of a Whipple Supercharger should make the Mustang over 500hp with a mere 4.6L imagine the 5.4L with one.
How many Mustang GT's are produced a year? How many GTO's? How many Cobras (past or expected present)? Other considerable deciding factors for most are which comes in convertible? Which has an automatic? Which has more parts available to include aftermarket? Which is made in America?
I've always had love for Pontiac. I used to love cruising with my '68 Lemans convertible with sidepipes I ordered from JC Whitney when I was a poor H.S. student. What a beat up project car that was but it turned heads wearing primer grey lol. Wish I could have restored it. Sold it to help goto College wonder if it's worth it looking back lol. I also have a love for the Trans Am and its killer looks. Thats one thing that I miss with this GTO, it has the looks of a Sunbird, nice interior but much left to desire. The Mustang was and seems to always be my true love. It allows us to create our own image at an affordable price. It created the tuner car market. The '05's looks are incredible. The interior is growing on me. When I went to the NY Auto show I had the pleasure to speak to a rep who said they are going to bring back as many of the classic names and styles as possible. This includes the California Special, Shelby, Saleen, Mach I, and so forth. Talks are going on with the late Mr. Shinoda's wife for use of the Boss nameplate and possibly a newer ASC Mclaren might be on the horizon. I am very happy with the direction of the Stang and hope it brings back the other pony cars like the Camaro and Trans Am. It's nice to see Hemi's around again too. Here's to a brighter future!

R&T showed the MSRP of the '04 Cobra to be $35,895, and the GTO to be $33,190 -- a $2,704 diff in favor of the GTO . That's about halfway to that 481 hp, 435 lb-ft, Vortech supercharger kit. The other half you could get from the fact that the '04 GTO was heavily discounted, while the '04 Cobra never was. Yet R&T chose the GTO over the Cobra, by 588.1 total points to 574.4. How much higher would the GTO have scored if it had been packing the extra 50 hp, 35 lb-ft, 18 ci, and better cylinder heads of the '05?
So when comparing either the '04 or '05 GTO to the '04 Cobra, at least according to R&T the "value" shoe is on the other foot.
> Motortrend also list the '05 Stang as 0-60 5.1 1/4 mile 13.6. I mis-typed the '05 Mustang GT's 0-60 as recorded by C&D. It was 5.1 secs, not 4.8. The '05 GTO was 4.8. Also, I copied and pasted the GTO's "strut, coils, sway bar; IRS, coils, sway bar" to the Mustang and didn't change it to "strut, coils, sway bar; solid axle, coils, sway bar."
> I have to disagree with your presumption of > this very new motor having a huge aftermarket parts source. Although Chevy is calling the 6.0 LS2 the "4th gen" SBC, it's really not a lot different than the LS1 that's been out since the 1997 model year. The "3rd gen" is also used extensively in GM trucks and SUV's (and ironically these engines run the LS6-style heads that the '04 GTO lacked). There are lots of speed parts out already -- cams, intakes, valvetrain upgrades, stroker cranks, blowers -- and with hundreds of thousands of Gen 3/Gen 4's on the road there is an ever-growing market for more.
Bottom line is, I am very uncomfortable with being the designated GTO spokesmodel in this thread comparing it to the '05 Stang. I love the new Stang, and I am as tempted to buy one as I have ever been in a lifetime of buying used only. But I like the GTO better. The bland styling -- which is the most often heard complaint -- is actually a plus to me.
And really, the reason I jumped into this thread is no one who imagines him/herself to be any kind of an enthusiast should EVER look down on anything with 400 hp. When I see all the genuflecting going on toward old heaps from the '60's that only dreamed of 300 hp, much less an honest 400 net hp, it bugs me to see the GTO so disrespected by the same crowd. There are VERY FEW muscle cars that could do a 13.1 @ 107 bone stock. Just Google up one of those "50 Fastest Muscle Car" compilations and see what I mean. In fact, I just did, and here are the TOP TEN:

ONLY 5-6 EVER THAT COULD RUN WITH A BOX STOCK '05 GTO!!! And just try to buy a '66 427 Shelby Cobra or a '69 ZL-1 Camaro, or any of these cars, for $32,295.

Just an FYI. It may be a geographical anomaly, but here in the northeast the '04 Cobra was indeed heavily discounted. At summers end the $40k anniversary convertibles were selling for as low as $30k. The amply produced '03 Cobra really dragged down the asking price of the late season '04s.
Saturday I saw an '04 GTO on a lot with "The Wild Bore" "$21,999." scrawled on the windshield. I don't know if the salesman is a genius....or disgruntled, but it got my attention. :) If you can get past the looks, it's a heck of a car for short money.

Keep in mind, when talking about 13-second cars, that a few tenths difference in ET may not sound like much, but it really shows up at the top end. Assuming a 100-105 mph trap speed, a pair of 13-second cars are traveling at 147-155 ft/sec. So the .4 sec diff between a 13.5 and a 13.1 is 58-62 ft, or 3-4 car lengths.
About the SD455, I got this from a quick Google:
"1973 saw some significant new changes to the Firebirds. . . . The first was the introduction of a new Super Duty 455 V8 (SD-455). . . . [T]he Super Duty 455 was a street legal race prepped engine. . . . Pontiac rated the SD-455 engines at a stout 310 bhp and 390 lb-ft, but experts agreed that it was closer to 370 bhp. . . . Unfortunately, Super Duty engines were expensive and therefore rare; only 252 Trans Am's and 43 Formula 455's received the SD-455 engine."
http://pontiac.sk/history.php
The same page says 943 more SD's were produced in '74. So total production was only 1,238. Then, as now, people didn't buy real performance in as great of numbers as you might expect.
The same page also cites a 13.5 @ 104 for a '74 SD.
A '74 SD 455 also appears as number 15 in the same "50 Fastest Muscle Cars" chart as I've previously quoted:
15 1973 Trans Am 13.54 @ 104.29 455 SD 310 automatic 3.42 HR 6/73

Whenever they do these comparisons, they put in only late 1960-1970s vehicles when in reality, the fastest muscle cars existed in the mid-1960s. Thunderbolt Fords and those ugly Chryslers that could whip off 1/4s in consistently low to mid 11's. The only cars to better them where the specialty vehicles like the late 1960s Hemi Darts and Barracudas that could drop into the 10's in stock form. -Rich

I think the 05 stang gt was able to outhandle the 04 cobra on a street course. solid axle vs irs. It's all about the implementation. The 03/04 cobra implementation of irs wasn't great, but the gto's isn't all that great either.

I liked your comments upto here. if we start throwing in aftermarket stuff you can compare all you want, the outcome will be different. Let's stick to stock for now.

There is no replacement for displacement. Already there's see above. If you replace the Gt500's blower with a KB (am sure they'll come out with one by the time the fr500 is on the street) it will blow the GTO away... heck, a pulley swap, chip mod and some other cheap mods will blow the GTO away, and a lot cheaper also. See what I mean ? I can keep reasoning here.

'05 GTO: wt: 3787; gear: 3.46:1; '04 GTO: wt: 3821; gear: 3.46:1. So the gear is the same and the weight is less (although a mere 34 lb diff may be accounted for by the weight of gas, the test driver, etc.)
These numbers are from the side by side test of '05 GTO vs. '05 Mustang in January '05 Car and Driver http://www.caranddriver.com/article.asp?section_id=15&article_id=8908&page_number=1 and the December 2003 test of the '04 GTO http://www.caranddriver.com/article.asp?section_id=3&article_id=7360&page_number=1 . C&
C&D also got a 5 mph trap speed improvement from the additional 50 '05 horses, and the '045 was 0.7 seconds quicker in the quarter. These numbers make sense. The Autoweek numbers don't.
Here are all the vital stats from the C&D stories:
'04 GTO:
0-60: 5.3. 1/4 mile: 14.0 @ 102; 346 ci; 350 hp @ 5200; 365 lb-ft @ 4000; wt: 3821; gear: 3.46:1
'05 GTO:
0-60: 4.8; 1/4 mile: 13.1 @ 107; 364 ci; 400 hp @ 6600; 400 lb-ft @ 4400; wt: 3787; gear: 3.46:1
'05 Mustang GT:
0-60: 4.8; 1/4 mile: 13.8 @ 103; 281 ci; 300 hp @ 5750; 320 lb-ft @ 4500; wt: 3575; gear: 3.55:1
> Again with 100 hp more then the Stang it is only > .3 seconds quicker then the Stang not 7 tenths > not sure were that came from. I got my wires crossed between Autoweek's numbers showing the '05 GTO being seven tenths quicker than the '04 GTO, and three tenths quicker than the '05 Stang. I meant to type "3" but it came out "7". For the GTO to beat the Stang by seven tenths would be OK (e.g., see the C&D numbers); three tenths from a car that's only 200 lbs heavier and 100 hp stronger and I say something's wrong.
> How about handling, breaking, price, > style? Handling and braking: From the C&D comparo:
'05 GTO: wt ft/r %: 53.8/46.2; strut, coils, sway bar; IRS, coils, sway bar; 300 ft skid pad g: .88; vented discs/vented discs; 70-0: 167 ft; '05 Stang: wt ft/r %: 52.5/47.5; strut, coils, sway bar; IRS, coils, sway bar; 300 ft skid pad g: .89; vented discs/solid discs; 70-0: 170 ft.
> Also aftermarket accessories. Potential for mods is where the GTO leaves the Stand far in the dust. First, it comes with IRS and an utterly bullet-proof 6-spd, while the Stang comes with a solid axle that will NEVER equal IRS in street handling, and the latest update of the failure-prone T-5. So the same aftermarket handling improvements to both will still leave the Stang behind.
And as far as the engines, well that was my point to begin with, that a 364 ci LS2 (that means with the GOOD LS6-style heads and the ability to pop it out to 400+ ci no problem) kills the GT mod motor off the assembly line, and with a few mods will kill the GT, the Cobra, AND the GT500 too. There is no replacement for displacement. Already there's a Vortech blower/intercooler kit for the '04 GTO http://www.vortechsuperchargers.com/products/yourcar/04_gto.html : 481 hp and 435 lb-ft @ 7-8 psi. That's with a stock baseline of 350 hp, 365 lb-ft. Adding the same percentage increases to an '05 puts you at 550 hp, 477 lb-ft.
Finally, as far as "value," the '05 GTO is already selling at or below list price. The '05 Stang is barely there. With added dealer profit of $5000+ the Stang GT verts are going for thousands MORE than the GTO. There's also the collectibility factor. I predict the GTO will be the Hemi Cuda of 2030, and the '05 Stang will be the '65 with the 289-2v. As in $1 mil for a perfect low miler, vs. $20,000. Remember, no one bought the Hemis when they were new either.
