I've used a few different sites that come up with 3 different numbers.
Specs are 3.484 bore, 3.976 stroke, 10.2 cc dome, deck height 0, gasket thickness .074
gasket bore 3.51. Cylinder head volume 48 cc's
The sites I've found vary by as much as 2 full points (13 to 1 up to 15 to 1) Using the same input data (some of the sites don't ask gasket bore size) I would think it shoulkd be within half a point.
