over-over-square
 

anyone know if 3.2 cylinders will fit on a 2.5 bottom end? the 2.5 has a shorter-throw crank, so 3.2 cylinders bored out to 3.6 with the 2.5 stroke would yield a 3.3 over-square engine that would rev to the stratosphere!

I think you are rich, if you are right ;)

You want me to reverse engineer a 3.2 head by slicing it 32 times, 3D scan it all back together, and remodel it with a 2.5 bottom-end?

You pay for the casting mold?! and I want 25% of sales revenues
