Default Re: piston to head clearance

Well, I guess I should have explained a little better on what I am building. I don't pretend to classify myself as an engine builder, but I have built a few small block racing engines. Since this is my first stocker build...I am trying to get everything that I can get out of this power-wise and knowledge-wise.

I am building a 307...just trying to go a couple tenths under...hopefully. This engine will not turn over 6000rpm to speak of, the piston rock is approximately.005 and on the high end it sits about .002 in the hole. I don't have a very aggressive duration cam and therefore am hopeing that is why I seem to have a decent amount of P-V clearance. I hope that I can get away with about .022 to .025 piston to head clearance to increase my compression as much as possible.
