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.
Should be able to find the current OEM replacement by contacting AC Delco.

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
Accel #276 is a non-resistor equivalent.
You can get them through Jeg's, Summit, etc. if you can't find them locally.

If he uses the silicon graphite wires the resistors are a good thing and perform well.
Ding ding ding. Get the Delco ones. The Accel ones are reboxed crap.
Buy from the folks that built it and know what's best for it :). Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 26k orig.

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.
Those should burn the valves right out of your heads within 12,000 miles.
I've been running R43S plugs for 3 years and a bit over 20,000 miles in my
70 LT1, no problems yet.Dave
ignore tarver, he's the resident retard...
The retards os this newsgroup are the whip out your dick gang.
The s tip version is bad for valves, but is used in some standard tip spark plugged GM engines after they start burning oil.
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?
The real difference is which heads a spark plug is designed to run in. The
46 is a hotter plug than the 45, although the plugs have the same tip.
So a 231 V6 (of which both plugs are designed to run on) differs in the same year?
NOT :) Joe--ASE Certified Parts Specialist & 10th Ann.Club Tech Director '80 Carousel Red Turbo T/A, 26k orig. '79 "Y89" 400/4 speed 10th Ann. T/A, 57k orig '84 Olds 88 Royale Bgm 2 dr, 307 "Rocket" (lol), 141k and still going.... '80 T/A project car...
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
So according to Tarver Engineering people should not switch heat range on spark plugs to adjust combustion?
Not only is that contray to all published data. It's plain wrong.
Tell ya what, stick to stuff you know. Charles
100% of nothing is?

The logic capasity of my Ex-G/F? Charles
I wondered what happened to wife #2
Ray spilled my beer when they jumped on the table and proclaimed in
Poncho/Dave knows this. He's the polite one here. :)
