I know that I need to calculate the volume of the head and then the cylinder. Can I do this in milliliters? Some thing about stroke also plus a division to get the ratio. I need to be enlightened![img]i/expressions/face-icon-small-happy.gif[/img]

Thanks!

 

Cylinder Volume divided by combustion chamber volume. That would be cc's so, multiply that by 100 I guess to get millimeters. Or Bore X Bore X.7854 X Stroke X Number of cylinders for displacement. I believe that's it...don't take my word for it.. OUT
