I know what you have in your truck, I said I would do a T-56. I definitely wouldn't put one behind a well built diesel, but I only have a 350. I just know that they make GV units that match up to a lot of the GM 4 speeds, but the ratio's for OD aren't what I'd like to get. I'd never looked into anything more than a 4 speed with it though. If your 6 is right around the same then it isn't worth it to me, but again, mine's only a 350.
