Ok,I'm doing a tune up this weekend and I would like some ideas on what plug is the best?AC autolite,hot or cold and part #"s.Thanks

Todd i think you need to be more specific with your engine combo. what kinda of heads and how performance oriented is the motor. in my 383 i run autolite 3924's there a buck a piece. but that is for aluminum heads that need a 3/4" throw. More info needed.

HEre is a site for cross reference and you can go by what you already have. good luck.
