If you want that static CR with a 4" stroke and 60 cc chambers, then do this:
- Use the ICON IC9978 piston from their FHR forged line. 13 cc dish + eyebrows, and CH of 1.450"
- Cut deck to get to that SCR and a decent quench gap with those 60 cc chambers with no chamber cutting
- Cut block deck by approx .022" to get the piston tops .005" below deck. SCR will then be 11.1 with a Felpro 1008 head gasket and quench gap of .044"
- Or, cut deck by approx .027" to get piston tops at zero deck. SCR will be then 11.2 with the Felpro 1008 head gasket and .039" quench gap
FWIW: Dynamic CR will be around 9.0 with those cam specs at 104 ICL. Don't know your exact elevation but at 500' cranking compression computes out to 185 psi + or -; the fast ramps on that particular cam (optimized for the .904 lifters) would make me thing it will be more on the + side.
Ought to be exciting! LOL
