Hi, I'm thinking about swapping a 6v53 into my 93 Chevy heavy half ton with sportside bed, I imagine the truck weighs somewhere around 5,000 pounds. I browsed another thread on here. I had decided on the Spicer ESO66-7B but seeing as I'm not sure if it's four wheel drive I don't know that it'd be my first choice as I'm looking for a four wheel drive project. I'm thinking that the top speed for this truck would be somewhere around 80 mph as that's the highest top speed in my state, assuming I can find a way to mount one would I be better with an early G56 transmission out of a Dodge truck or should I go with the Spicer and mount a remote transfer case? I already know I'll need to change the springs on the truck because the v53 is a lot heavier than the tbi 350 and even the 6.5 Detroit, I'd be fine with changing the axles to something like a full float 14 bolt so I can have both the proper gears and a locker instead of the open diff of the semi-float 14 bolt. Thanks in advance.
