Car Forum / Chevrolet / Chevrolet Camaro / April 20041970 Camro Spark plugs
Hi all. I have a 1970 Camaro with a 350 250 HP motor in it. I would run the AC 44 spark plugs in it. Now I find these plugs are no longer available. Any body know a good replacement plug to use? Thanks for any advice or comments. Have you tried the AC R44? That's just the resistor version of the same plug. I know resistor plugs don't sound good, but in reality they usually run just as good. You could also try Accell. I believe they still make an equivalent version of the original non resistor plug. - Gary > Hi all. I have a 1970 Camaro with a 350 250 HP motor in it.

You can get them through Jeg's, Summit, etc. if you can't find them locally. -Matt- "..." > > Hi all. I have a 1970 Camaro with a 350 250 HP motor in it. I would run > > the AC 44 spark plugs in it.

Accel plugs are reboxed NGKs... Or used to be..havent bought a set of them in about 9 years..so they might have changed vendors. > You can get them through Jeg's, Summit, etc. if you can't find them locally. > > -Matt- "..." > > > Hi all.

I think they're reboxing Denso plugs now. Still Japanese... -Matt- "..." I ended up with AC R43S spark plugs. GM Claims it's the replacement plug for the old AC R44. Thanks for all the advise & comments. > > > > Hi all. I have a 1970 Camaro with a 350 250 HP motor in it. I would > > run [quoted text clipped - 12 lines] > > -Matt- "..." Last time I looked, the Accel are Denso U Groove plugs and work well. The last set of resistor AC's I used in my high performance 350 missfired over 5500RPM. > I ended up with AC R43S spark plugs.

Those should burn the valves right out of your heads within 12,000 miles. > > I ended up with AC R43S spark plugs. GM Claims it's the replacement plug > > for the old AC R44.

I've been running R43S plugs for 3 years and a bit over 20,000 miles in my 70 LT1, no problems yet. Dave >>>I ended up with AC R43S spark plugs.

The s tip version is bad for valves, but is used in some standard tip spark plugged GM engines after they start burning oil. > > >>>I ended up with AC R43S spark plugs.

As normal, wrong. And no..they are not bad for valves...the lack of lead in the fuel, used as lube for the valves, is bad for the valves... Tarver...get a clue...will you? > And no..they are not bad for valves... Yes my idiot, changing to the hotter tip is bad for the valves. that is why GM made both kinds of plugs in the first place. Please stop posting your ignorance to this newsgroup. If anyone wants to know how to have a non-operating f-body they will ping you. > > And no..they are not bad for valves... > > Yes my idiot, changing to the hotter tip is bad for the valves. that is why > GM made both kinds of plugs in the first place.

Tell me Tarver...other than give wrong advice in here, and in the aviation groups....do you have a f.cking life? While you are at it, how about telling us again about that Hemi..(LOL) inline 6 you talked about that went into..what year was it......89??? Firebirds... Sheesh...little man, do you even know how to kernal set your plugs? Better yet...do you know what it means? I have no wish to take a side in this as I don't have much of a clue about it. I just want some confermation on a couple of general principles: 1. Hardened valve seats and valves remove the requirement for lead in gasoline and allow the use of unleaded gas. 2. Catalytic converters choke on leaded gas and need you to start the combustionion process sans lead in the gas. Are these principles true, false, mostly true or what? >> > >>>I ended up with AC R43S spark plugs.

You are correct...the lead will bond to the converter, and clog it... > Are these principles true, false, mostly true or what? True, however, we were making a comment about pre-converter vehicles.....GM didnt have a vehicle in 1970, the poster that I was making a comment about, that used a converter. > >> > >>>I ended up with AC R43S spark plugs.

An AC R43S is actually one step colder than a R44. The "S" just means the electrode doesn't extend as far into the chamber as the standard plug. "S" means short. The number is always the heat range with AC plugs. - Gary > > >>>I ended up with AC R43S spark plugs.

Ray spilled my beer when they jumped on the table and proclaimed in <sFkjc.269458$Ig.4105@pd7tw2no> > ignore tarver, he's the resident retard... Poncho/Dave knows this. He's the polite one here. :) NOI > Ray spilled my beer when they jumped on the table and proclaimed in > <sFkjc.269458$Ig.4105@pd7tw2no> [quoted text clipped - 4 lines] > > NOI I had to show this to the wife. She is amazed anyone thinks I'm polite. ;^) Speaking of sparkplugs, I got an hour or so to flip through a NASCAR engine builders guide and came across something interesting about spark plugs. The funny part is the guy who runs the dyno I'm using now said the same thing I read but his information is based on dyno runs at the shop. Say you buy a set of R43S (or other applications) plugs for your street/strip car. Don't bother regapping the plugs to a wider gap to make more power. It doesn't make any more power than if you just check them for consistent gaps. I tried it myself dropping from 0.045 to the 0.035 from the manufacturer and didn't see any change at all. You'll pick up more power switching to a synthetic oil (not much but it could change a 12.05 into a 11.99) than wasting your time regapping your plugs. I'll bet the big boys at the strip have other ideas but till I'm making over 1200 hp I don't think I'll have to worry about it. ;^) YMMV Dave |
