I know this is old, sorry but im new and wanted to help a little.
The formula is ((Bore/2)^2) x Pi x Stroke x 8 or
Bore divided by 2 then squared, take that times Pi (Pi = 3.14159 etc.) times Stroke times the number of cylinders. So 4.300 would look like....
I AM NOT THAT GOOD WITH MATH
BUT I WAS TOLD
BORE x BORE x STROKE x .7854 x 8
SAY
4.500 BORE
AND
4.500 STROKE
=572.55
WOULD THAT BE RIGHT
I AM JUST CHECKING TO SEE IF I WAS TOLD RIGHT
THANKS
GEORGE
if you ask why check it .7854 x 8 = 6.2832 it just leaves out a few steps and much easier to remember...
