The increase in displacement for a 0.030" over bore depends on the size of
the engine. Here is the formula for calculating the displacement of any
engine:
displacement = pi * (bore / 2) * (bore / 2) * stroke * cylinders
Note: The approximate value of pi is 3.14159
Using this formula, here are the results for a few different engines.
---------------------------------------------------------------------
283 net increase 4.399 in3
0.030 (287.437)
std (283.038)
350 net increase 5.269 in3
0.030 (355.291)
std (350.022)
396 net increase 5.824 in3
0.030 (401.795)
std (395.971)
502 net increase 6.764 in3
0.030 (508.938)
std (502.174)
btw, I am working on a set of 'Calculators for Gearheads' and will let you
all know when I get the page(s) posted. If you have any requests, ideas
and/or formulas to share, email me off the list at [EMAIL PROTECTED]
