[QUOTE="TreeClimber, post: 791044, member: 16101"] My 79 had a T18 with 6.1 first. Backed with a Dana 300 and 2.62 low range. Now I'm running a TH400 with Atlas 4.3. You'll never regret the change! I even get compression braking on steep descents. I orginally had a low low stall converter, but changed it out for the stock Chevy stall. In a short wheelbase, the doubled t-case take up too much room. Go with an aftermarket case, or a D300. If you're a long wheelbase, then doubled cases makes sense. And I only run one cooler, but it's designed for a 2.5 ton truck. :D Never-ever-ever gets hot. Even been in 100 + outside, pulling mountain passes up to 11500 feet. I do however run an auxilary fan in front of the cooler when wheeling hard or pulling passes, etc. I'd run a overdrive, if higher than 4.56 axle ratio on tires 37 and under. You can build an 700r4 to hold up to abuse, if you spend the $$. Tony [/QUOTE]
