Just get the information the form asks for and it will calculate your c.r., if you have dish pistons, need to know the volume of the dish in cc's, how far the piston is down in the hole at TDC, typically .025", compressed gasket thickness, typically .041", etc.

We could guess at about 9.5:1, but...
