If your ever in a bind go HERE
327 was the same as a 350 it just useds a 3.25 inch stroke crank instead of the 350's 3.48. So in other words org. bore is 4 inches 4 over gives you 4.040 Then if you look on the page you wil lsee 40 over next to 327 and you will see 333.293... and there ya go Chris Last edited by strikingthematch; 04152005 at 09:00 PM. 


The volume of any cylinder is: PIE ARE SQUARE TIMES LENGTH. PIE ARE NOT ROUND IN MATH. PIE IS ROUND AT THE GROCERY STORE.
Of course the length in an automotive engine cylinder is determined by crankshaft stroke. Who was asleep in 9th grade geometry? 


Geometry?
Gee I was taught the formula for finding the volumn of a cylinder in 6th grade math class, but then that was back in the days when teachers could read and write better than that students.

Good call brian. Not to be a jerk (heck, we've all made some poor calculations in our time) but for crying out loud, finding the volume of a cylinder is pretty basic stuff. After having been through basic high school algebra, we all should be able to do this stuff without needing 10 replies to give directions. The proper way to do it is Pi(radus squared) mulitplied by stroke (or height of cylinder) and then by the number of bores you have. K Last edited by killerformula; 04172005 at 01:12 AM. 


One more way:
Area of the circle,times height. Paulo
