Car Forum / Pontiac / Pontiac Firebird / January 2007Blowing smoke up my a.s ?
" All the earlier Cameros ie 70 -76, had big blocks available as options, and engine bay didn't really change from 70 to 82" Is this statement accurate ? I know he misspelled Camaro but/and I just dont think he knew what he was talking about. Longer engine bay because of an engine option? I don't think so... Pure smoke. >" All the earlier Cameros ie > 70 -76, had big blocks available as options, and engine bay didn't really > change from 70 to 82" > > Is this statement accurate ?

Under the hood didn't change very much right up through 81'. The largest changes came from emissions which really took up room under the hood. The Birds had the 400 Poncho and 403 Olds up until 79' I think, could be wrong on that one though. 72' is the year you can go back to him with. Government regulations killed the big blocks after that, going from gross to net and the emissions thing. ...Ron -- 68'RS Camaro 88'Formula 00'GT Mustang I think that '73 was the last year for a big block. 70 to 81 Camaro's had almost identical engine bays. >" All the earlier Cameros ie > 70 -76, had big blocks available as options, and engine bay didn't really > change from 70 to 82" > > Is this statement accurate ?

Thank You all for the info > " All the earlier Cameros ie > 70 -76, had big blocks available as options, and engine bay didn't really > change from 70 to 82" > > Is this statement accurate ? I know he misspelled Camaro but/and I just > dont think he knew what he was talking about. 1973 was the last Big Block Chevy for the Camaro. 1974 was the last year for the 455 in the Trans Am. Since all Pontiac V8's except the 301 are the same external dimensions, the motor is often confused as a big block. The Olds 403 was available from 1978 to 1981 in the Trans Am. 1974 Camaro to 1981 was available with either a Chevy 350, Chevy 305, Possibly a 307 in 1974, a 265 in 78 to 81 California Cars, a Straight Six from 1970 till 1976, then a 3.8L Chevy 229 CID V6 from 1977 until 1981. Any Chevy that was available with a Straight Six has the length under the hood for a Big Block with Truck Accessories. Width on the other hand is a issue on some cars. The Straight Six is heavier then a Small Block Chevy! Yet the V6 is lighter. So with 6 cylinder cars if you V8 them you must change springs unless you want odd ball stances. As for the Big Block Chevy it was available in until 1976 in Chevy Impala's & Kingswood Station Wagons. This maybe where the person in question got the facts confused. The Big Block Chevy was still available in Truck, and at your GM Dealers parts counter. There were some New Car Dealers who would Install a LS7 (parts counter only) 454 in your new Camaro threw 1981. While it was a violation of Emissions laws, in states with out Emissions Testing, things like this could be done with out much concern. Charles P.S. Last Year for the Big Block Corvette, 1974. Never really got a good answer on this one (maybe I just can't remember:). Does a big block fit in the '87 Trans Am? What kind of conversion is necessary? I know the exhaust is an issue but how much (conversion headers, steering shaft, trans mating, crossmembers & mounts, accessories?)

Last Year for the Big Block Corvette, 1974. I'm sure they do make a kit to put one in the 3rd gen camaros, should fit in the Trans Am. also here is an article on what they did back in 82 to make one. http://camarotech.com/Gen3-BigBlockSwap.html > Never really got a good answer on this one (maybe I just can't > remember:). [quoted text clipped - 40 lines] >> Charles >> P.S. Last Year for the Big Block Corvette, 1974. Ya know, I was thinking about the possibility of a true Pontiac engine. 455? Don't know anything about Pontiac motors other than they have funny-looking heads that feed into the exhaust. But, I understand their block size might be something between big and small block Chevy's; a helper for an oversized engine here? Thanks for the link.

Last Year for the Big Block Corvette, 1974. Might be the better way to go. Here is a site to check out. I know they have motor mount kits and headers. I think they can supply you with everything you need to drop a 326-455 into a 82-92 TA. http://www.chiefmanyhorses.com/ Go to their online catalog. Go down to headers, then go to motor mount adapters just look thru it they have everything for it... > Ya know, I was thinking about the possibility of a true Pontiac engine. > 455?

A Chevy V8 is a Chevy V8 when it comes to bell housing bolt patterns. As for the mounts & exhaust, that all depends on what your going to do with the car. While it's not rocket science, it is basic chassis science. Change one or two variables and it changes all the answers. Can it be done, Yes. Is there one "kit" no. There are a few. I don't use "kits" I either fabricate the parts, use other pre-made parts, or have the master fabricator buddy of mine fabricate them. The only way you will get a detailed answer from me is to drop off the car, and leave a large deposit. Charles Yep, figured I'd get it for the transmission mount but better to ask than to learn a dumb lesson when I was sleeping. Wish I had a master-fabricator buddy and I'd ask him. Heck, if I had a large deposit, I wouldn't be here right? Haha! Best Regards, Drink >> Never really got a good answer on this one (maybe I just can't >> remember:).

Haha! > Best Regards, > Drink Having a buddy that can narrow rear end housings, build N.H.R.A. Legal roll cages, back half frames, or complete tube frames is nice. Yet he don't work for free, but he does know his stuff. All part of living in a town where Manufacturing, tool & die business and the machine shop business used to be king. You meet all sorts of people who have skills you never could learn going to school for the rest of your life. As for money? There used to be some rather well off people that posted here some years back. Heck back then I had 3 times the income, 1/4 the over head, and worked maybe half the hours I do now. BTW: you never have said the intended purpose of this big block 3rd gen?

The 455 was dropped in 74 but it was brought back in 75 and 800 some 455s went into Trans Ams as 455 HOs but the 124 cc heads only produced 7.6:1 compression and 200 hp. The 455 was continued into 76 with pretty much the same heads and horsepower rating, about 7000 sold in 76. The 455 could only be ordered with the M21 transmission option which was a BW ST-10, the TH400 wouldn't clear the pancake catalytic converter. dave |
