Compression Question I am going to put .030 milled LS3 heads using .041 head gaskets on my LS2. Can someone give me a compression ratio estimate with this setup?
Thanks
Thanks

This won't be accurate but just to give you an idea. Since the heads are milled .030 I would assume that would take the chamber down to 62cc from 70cc. Your gasket bore is 4.080 and with a flat top piston on a 0 deck it would come out to 11.53:1.

Thanks guys for the info. I never measured out of the hole, it is a stock LS2 bottom end, I am not sure if there is a standard out of hole for an LS2 or if all engines are a little different. Thanks for the replies, I will see if I can get a meausrement for out of the hole, I am guessing you would use a dial indicator to measure that distance, I know it isn't much if any.
