Next few Questions......

I have started 3d modeling the piston, conrod and head and crank because: I can, I'm sad, theres sod all else to do during my lunch hour!

Could anyone tell me the throw on a cosworth crank? How thin can you take a piston crown?

In reply. I have bought the pistons (2nd hand all be it) and they were delivered yesterday. Is there absolutly no way they can be used?

What can I get away with porting to? Are there any books that can tell me the angles and depths involved? or does anyone know?
