4L80E to power Glide? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm thinking it will be easier to get hooking.. It had no problem hooking that on the motor with the 4,900 stall. The 3.73/4L80E technically is shorter geared than the 4.56/PW set up. 3.73/80E @ 7,400 in first would be 60mph, where the 4.56/PW combo would be 74-77mph depending on the first ratio. That's one of the reasons I think I could get on the unit sooner.

I'd also probably drop the verter quite a bit, probably 3,500-3,800 knowing it's going to have gobs of TQ with the N20..
