Hi Everyone,

I have a rebiult (last week) the orignal engine from my 57 BelAir. Its a 283 2bbl of course, I`m looking for the Correct A/C Spark Plugs for it. Anyone know the ac plug number and where I can get a set ? I`m going for a points car and want it right.

thanks in advance,

You won't find those spark plugs except from NOS/NORS type sources. They don't make them any more. Try Ebay or Hemmings.

What would be a good plug for a 265 V8 with HEI? :confused0006:

You need electronic ignition with resistor plugs

The problem I have with the new resistor plugs is they dont work very well with points ignition and the ethanol gas make,s it even worse. Back when we has good red leaded gas a small block chevy needed the plugs changed about every 10,000 miles. I always used a 46S ac plug. Randall
