displacement calculator?
I seem to remember an online displacement calculator if you put in stroke, deck height, and crank size..... anybody remember the link? (I can't find it in a search.....)
Is this it: bore x borex3.14x stroke=???
so 84.5 x 84.5 x 3.14 x 95 = 2129cc?
OR
Bore x bore x stroke x # of cyls x .7854 = displacement
84.5 x 84.5 x 95 x 4 x .7854 = 2131cc?

crank size aka stroke
V = (r² * Pi * Stroke * # of cylinders)/ 1000
In my case, V = 84.5 squared x 3.1415 x 95 x (4) and divide by 1000
Which is 2130
I'm second guessing the formula as I got some differences in my calculations.....

Anyway, its bore x bore x stroke x .7854 x number of cylinders.</TD></TR></TABLE>
Yeah on me, I was typing faster than I was thinking..... anyway, I'll round down and call it a 2.1L motor.
