    ENGINE SWAP -or- SELL! the final say for the most efficient square body motor!

    Let's face it, we don't really own these trucks because of their outstanding mileage per gallon, I have an 06 duramax that gets over 20 cruising at 75, " towing is a different story". but to tell you the truth I like driving the 85 around town, Buy a commuter and keep the square.

    little more H/P and Torque

    Just some cheap H/P, Here's what I want to do: I picked up some 062 heads and an intake manifold to match to use my carb, I also have the roller lifters, but after wanting to go all the way I thought I'd start by just adding the heads, and a flat tappet cam no more than a 160-180 lift as that is...

    1984 short box suspension lift 4" or 6"

    The only thing to be concerned about with more than 4"; and your running a 208 transfer case' is the slip joint, I found a 241c for my 85 and now have a slip joint eliminator. The 208 slip joint will be your weakest point and cause you problems.

    axle swap

    My Local gear and drive line service confirmed: any truck 12 bolt 30 spline shaft will work, just need different carrier bearings, I also have done a lot of research on the length and confirmed that you can get 30 spline axles the exact length 87-91 10 bolt 8.5 31 5/16 (.313) or 70-81 12 bolt...

    axle swap

    Here is a quote I was referring to; seems pretty strait forward. I have been sitting on this info for while and have only seen a hint of it in the truck sections. We all know the GM 8.5 corp diff.vers the 8.875 and 8.2 Did you know that the 8.5 pinion is the same physical size as the 12 bolt...

    axle swap

    I also read that you can put 30 spline 12 bolt axles into a 10 bolt 8.5 with a 30 spline carrier. Anyone ?

    axle swap

    I picked up a eaton detroit suregrip for an amazing price, it is for a 8.5 or 8.6 30 spline. I'm not sure if my axle shafts are 28 or 30 without removing them, Question is:; does any body know what make and part number I would need to replace the 28 spline axle to 30 if need be. Thanks

    door alignment

    Changed my Hinge pins yesterday and I thought that would take care of the body line issues, the door shut nicely but I just couldn't leave the body line alone. I tried to sneak a variable amount of tools to loosen the hinge bolts and got two loose but that was it. I decided to dig in and take...
