All else being the same, just wondering what affect going from a roughly 70 pound crank to a 40 pound crank would make performance wise(other than taking 30 pounds off the front of the car)

My steel 4 incher is close to 70 pounds, i know the callies and others come in a good bit less weight, and "trick" cranks can be 35-40 pounds.

Big "rev" difference???
