That will cover the transmission. What about the differential, U-joints, & half-shafts? I think if you double the HP, you will have problems with your 'pumpkin' & standard 190HP U-joints.

It's been said here before, The rearend can handle 600hp with street tires, 400hp with slicks. Of course those numbers go down with age.

I'm not sure why anyone would spend the money for an engine that will make 500-600 HP, then put street tires on it so that it won't break. If you only want to spin the tires, spend a lot less on the engine.
