13:1 Compression Pistons in 340 Small Block

So if I wanted to run these pistons what type of lift for a cam are we talking? I’m probably gonna port the head I have or the ones I pulled I think are already ported I’ll have to check.

its not the lift, its all about the overlap and duration somewhat so you can bleed off compression. the higher rpm range with the cam is what makes the horsepower. it rev like a chainsaw and not have alot of low end torque. it would not be a very good street motor.
