I only worry about rod stroke ratio from the standpoint of reducing piston speed, and increasing the durability of the engine by reducing the piston speed. I have seen a lot of testing that proves to me that rod stroke ratio does not affect performance that much. It does however affect the life of an engine.

Yes I know these are Chevy guys, but an engine is an engine.
