Hi Tim, As I understand it, the diameter of the 301/318 pistons is the same but the installed height would be different since the 318 crank has a longer stroke than the 277/301. So you COULD install 318 pistons in a 301 but you'd have very anemic compression, if you put 301 pistons in a 318 you would have mondo compression or possibly interference. Someone can correct me here if I'm wrong. I may need some 301 pistons myself here directly Tim. I'll get back to you on that though. Loren
