    I have an 83 with a 6.2 and 3.42 gears with a 700 and 33s. I get about 20mpg average. I have to tell you though, the motor is so underpowered I can't put it in overdrive till I'm over 65mph because the rpms are pulled down so much (1340rpms at 55 mph). It's so slow in fact I'm thinking about slipping in a 350. I think all diesels were 3.42 geared, unless it had an optional rear. I would 4.10 the truck at least with 35s.

    It really needs a turbo. Adding one to a 6.2 is a good idea and not difficult. They do very well with about 7psi constant boost. The stock 6.5 turbo passenger side manifold is a bolt on and any of several turbos fit the flange. If you have A/C you will need to surgery on the A/C housing for clearance or find a van A/C housing. Another idea is to buy a bolt on kit from Banks.

    You could also use van injectors if you have an ac truck, for clearance purposes. JS
