Compression Ratio for an ls1 with 58cc heads?? Ive looked around and cant seem to find the info im looking for. I have a stock ls1 bottom end, with a set of prc 2.5 5.3l heads with 58cc chambers. Im trying to figure out what the comp ratio would be with this combo..If anyone could point me in the right direction it would be much appreciated.

You will be over 11:1 with 58cc chambers-closer to 11.5:1 even without using a thin gasket.Hopefully someone will post a link to one of the compression calculators so you can figure it exactly.

What #'s did you use?
I got 11.4 after putting in the numbers. But that is with 0 out of the hole I'm not sure what you have but I doubt that it is .000 out of the hole.
