or the old fashioned way. its something like:
(PI/4)*(Bore^2)*(Stroke)* 8(# of cyl)

Re: Formula to Calculate Displacement? Stock bore is 3.9"
Stock stroke is 3.62"
The formula I use is an old one.
First find the area of a cylinder: pi( 3.1416) times the radius squared, times the length of stroke.
Then multiply that by 8 for the # of cylinders.
For a stock motor it would look something like:
(Radius for a stock 3.9" bore is 1.95)
1.95 X 1.95 = 3.8025
3.8025 X 3.1416 = 11.945934
11.945934 X 3.62(Stroke) = 43.24428108
43.24428108 X 8(# of cylinders) = 345.95424864"

Re: Formula to Calculate Displacement? Well it would be 3.62 stroke x 4.00 bore =363.92 right?
Using Ryan's link here's my specs...
4.060 bore x 4.075 stroke =422.05ci... so it works. <img src="gr_stretch.gif" border="0">
