I know that I put it up there so those reading this thread could compare the one you have to the ones that I listed.

"Want more top end with your heads put that 252-260 Lunati Hyd Roller in it - Have it ground on 108 LSA. " ( Put it in at 100 ICL )

Static C/R is the ratio of the cylinder volume at TDC verses the volume at BDC

Example:

351 CID /8=43.875 cu. in. times 16.38716= 718.986645 cc's At BDC

TDC= Chamber vol, + Gasket vol, + valve reliefs, + deck clearance, + distance to top ring. If you have a dome piston then you have to subtract that vol from the above.

Chamber= 66.5
Gasket= 9.3 - 4.100X.043
Piston= 7.0 - No dome 2 eyebrows
Deck = 0.0
Tot = 82.8 cc + 719 = 801.8/82.8= 9.68 to 1

Engine tech is all about the math learn the math and you can learn the engine dynamics!!!
