( 1/2 of bore) squared * pi * stroke * number of cyls.

eg

4 inch bore 5 inch stroke 8cyl

( 4" / 2 )squared * 3.1415 * 5 * 8 = 502 cubic inches

- Dan

stroke X piston radius^2 X pi X # of cylinders

Mabe next year when we freshen up the motor. For now, since it is a brand new race team and we smoked the motor the first race <IMG SRC="smilies/frown.gif" border="0"> I decided to build the motor with a stock (hardened) crank and upgraded everything else (forged rods, roller valvetrain, aluminum heads) so when we finally learn how to FINISH a race, we can up the horsepower by stroking the motor and go for the win. <IMG SRC="smilies/biggrin.gif" border="0">

And if he had 3 more, you could put one for each wheel! 4 wheel independent drive! Get It!
