Compression ratio calculators??

In doing a little number movement with most of the on line calculators I think they are not figuring the dome vol. + or - properly in the formulas.
Art,
Daves formula was the one I had at the shop that I said I would PM to you.

Mine also converts everything to cc's so i can do a "pour check" with a burette thru the spark plug hole as a double check before the motor is sealed. At least we've found some consistency in a couple of programs.... Everybody have a good thanksgiving.
