View Full Version : PTV clearance with 58cc heads and stroker cam

11-21-2010, 01:03 AM
I don't have a extra set of heads lying around and was trying to calculate if 58cc heads will be fine with a 247/255 114lsa cam in a 408 w/ Wiseco -3cc pistons. I wanna try to get my compression up so wanna see where I can get to. Thanks in advance.

P to V will not be a problem because you have pistons with valve reliefs.

I came up with 12.8:1 with LS2 stock gaskets of .054" x 4.050" and the piston out of the hole .008"

Are you trying to run on pump gas?

Here is the calculator that I use.
