Re: Using a Super T-10 4spd behind a GM??

Mongo, I have watched some of your projects so I know that you know what your are talking about. If you were anyone else I would be asking if you are thinking of th NV3500! My k20 had a 465 factory and I pulled it and installed a nv4500 out of a dodge diesel. I lost a little first gear but not enough to really notice it. With 4.10s and a big crammed 400sb it could use 4.56 gears but first is never the issue. I use first to get up my driveway in 4x4 or moving loads of oak to the wood pile. The nv4500 got pulled out of the dodge because it was making some death noises at full boost on a built 12v and got replaced by a 6spd. That 5spd has hauled over 16k trailer with 3.55 gears without issues when it had well over 1000ftlbs of Cummins power. Yes I abuse my trucks
