Reply to "Compression too high?"

goodrocMember

Steve, if you give me the following numbers I will be happy to calculate your exact compression ratio.

1) Bore
2) Stroke
3) Design volume of Piston (i.e. -3 ccm)
4) Design volume of Chambers quench (i.e. -58 ccm)
5) Extra quench (from top of Piston to Deck)
6) Head Gasket compressed thickness.
7) If you have a Cam Card with the specs of your Camshaft, I can also calculate the Dynamic Compression which is actually the more important one.

You can lower the compression ratio by using a thicker Head Gasket. So its not the end of the world ;-)

But judging by the Photos it looks like a high compression ratio.
