340 Piston Selection

Well, yes, but, even though the pistons are for a 340, not all pistons have the same features. Domes, valve reliefs, height, weight, etc...

Don’t get to hung up on the compression ratio. 1pt. Is roughly 3-5% in power. I know it is a big help with large cams.

Speaking of which, have you a cam for this?
Any ideas on its duration?
