Great.. more fun with the calculator..
It depends a bit on the deck height but here goes:
40 thou over = 1767cc, = 441.8cc per pot
std combustion chamber =38.6 cc
head gasket = 4.1cc
land volume = 0.6 cc
volume above piston at tdc = 2.0cc (assuming piston to deck distance at
tdc = 0.015 inch
total combustion volume = 45.3 cc
C/R = (441.8 + 45.3)/45.3 = 10.8:1
I've include the working for if you want to adjust anything, or if anyone
else on the list notices something that's not right (let me know too)
