guys I need to understand this when I saw fast's reply I became confused....believe me all this was meant in a positive light and meant to learn from.

Here is the way I have done this...please point the error of my ways.
1/2 bore times itself 2.25x2.25=5.06
times pie 5.06x3.14=15.89
times stroke 15.89x4.625=73.52
time ci to cc factor 73.52x16.387=1204.77 I rounded this to 1205cc

add head cc 1205+76=1281
add gasket cc... use same formula as above but used4.56 for bore and .074 for thickness
times ci to cc factor 1.20x16.387=19.66 I rounded this to 20cc
1281+20=1301
add or subtract deck vol which in this case is -1 based on a -.500 perfect deck vol. of 130cc
used same as above but used 4.5 for bore and used .500 for thickness

1301-1+1300
total vol at bdc 1300

ok
vol at tdc would be 76cc+20cc-1cc=95cc

1300/95=13.68
