hi I have a 1970 Plymouth duster with a stock 360 in it with a two barrel lol I know the two barrel has to go anyways it currently has champion plugs in it and I want to change them what is a good plug to go with?
Ok got it thanks would Napa auto parts have these?
what's wrong with champion plugs ?
Does Autolite have an equivalent to the RC12YC with 5/8" hex?

They work for me....So the ngk v type are pretty good too huh?
Too cold. The factory used N13y Champions. Autolite says their 65 or 66 is the same plug. Use Champions that the engine came with. If you modify the engine then you can mess with heat ranges.Autolite 63's
You could ask this question all day long and you would most likely get different answers for 90% of the people...
NGK GR5 work well for me too. The part stores cross the factory plug over to an NGK GR4, but that was a too hot of a plug for my engine.

The guy that built my 360 (Bob Lambeck) installed n65y plugs but they caused noise in my stereo system being non resistor.Too cold. The factory used N13y Champions.
