Default Help finding static and dynamic CR

Im not sure how to find these out but I wouldnt imagine it would be too hard as Im relatively stock. Im running a stock ls1 with 317 heads(ls6 yellows and chromemoly pushrods), GM gasket and TTY bolts. Thanks guys

I ran a calculator and got 9.7:1
This is what I put in:
bore 3.89
stroke 3.62
71 cc chamber
.51 gasket thickness

Does that sound about right? Sorry, this is my first build lol

.51 thick gasket? That is over a half inch.

Most LS engines have the pistons slightly outa the hole caus GM was smart, anyways they are usually .005-.007 so you are more like 9.75:1
