compression help
 

I was wondering if anyone knew of a site to help calculate compression.
The pistons I am looking at are a forged flattop with 4 valve reliefs.
The summit mag says they are 10.01:1 with a 54.5cc chamber. This is achieved with a .034 deck. The motor it is going in is a zero deck and the heads I have are a 60 cc chamber. any clues how to figure this out or what it might be??? any help would be appreciated.

Well I guess on the other parameters like stroke, bore size, piston wall clearance, piston size and valve reliefs and gasket thickness but if they are all stock then you will have 9.43:1

If you go to www.corral.net, go to tech features, then calculators and you'll see the one for compression.
