THERE it is!!
I just knew building an engine required fresh PI(E).
But your equation gives him a 1907353.88895744cc engine.
It's actually:
((bore/10) x (bore/10) x (stroke/10) x (3.14159265 / 4) x cylinders))
/10 puts BORE and STROKE in cm, not mm
OR, since we have a 4 cylinder engine we can use:
(bore x bore x stroke x 3.14159265)/1000
rather than dividing the bore and stroke by 10 abd pi by 4 and then
multiplying the result of that by 4 again
so,
8.8 x 8.8 x 7.84 x .785398162 x 4 = 1907.353887743 cc
OR
88 x 88 x 78.4 x 3.14159265 / 1000 = 1907.353888957 cc
for 88mm pistons and a 78.4mm stroke

Did anyone answer the question?
It's bore x bore x stroke x 3.14159265

I cannot remember how to figure engine size. I supposedly have a
1904. When I had it built 9 or 10 years ago I was told it was a
1914. It is 74.8 x 88. If I just multiply that I get 6582.4
which would mean I have a 6 ½ liter engine and I am pretty sure
that is wrong. How do I get to 1914?
