Assuming your measurements are good (no calculator is any good if the measurements are guesses and assumptions),wallace gave me 9.57 . Frankly i was surprised it was that high with the pistons that far down the hole..... then i remembered the steel shim hg, and the closed chamber head.
With a typical 906 head and a composition gasket, thats a high 7 to 1 engine.

You guys are awesome...I appreciate you all. I'm going to go forward with what you all have come up with. I'm obviously inputting something wrong...At those numbers I'm completely satisfied. Thinking about dropping this drive train in a custom hot rod...and just received my Keith Long transmission back for my '88 short bed...I got some work to do. Thank you all!
