Compression Ratio Calculation
Here But I'm missing some info to complete it. I have head volume, cylinder bore and crankshaft stroke but the other ones I'm not sure of. Can someone please tell me or point me in the right direction. And one more thing what is the stock head volume?

Re: Compression Ratio Calculation
I don't know what pistons you are using. But typical flat-tops with valve reliefs are
-5cc and stock deck is 0.020". Do a search on the CC volume, Arnie has measured it. But your's may differ if any work was done on the chambers.
