Peaked 100 Rpm sooner then old motor, torque was actually 1-200 higher on this bigger motor, Lenny has my numbers for the conv change. I've changed a lot on the car to help with added power I added sub frame connectors, and lost some weight to offset the added weight of the block!! It may end up a tad lighter well see.
