Here is what I currently have:
1995 2wd Extend Cab 6' bed 1500 truck with a 4.3L V6 and a NV3500 5sp manual. 160,000 Miles I think the rear axle is a 3.08 ratio.

The 4.3 is starting to get weak, and it is backfiring when I engine brake down hills. Blew up the muffler last week, probably just bad spark plug wires, but I am looking around to replace the motor. I called my Uncle who has about 6 of the Detroit Diesel 6.2 and 6.5 blocks at his house. He has been running these engines since they came out in 82. He said I could have an engine and everything I need to swap the engine short of the radiator for $100.
One particular engine he said is a 1982 6.2L naturally aspirated and he says it has the "big valve heads". (I asked him to take pictures of all of the casting numbers, I should have these in a few days) He will include the starter, exhaust manifolds, water pump, engine mounts, harmonic balancer, and the brackets for the AC and Alternator.
I plan to use a 1995 6.5L Turbo radiator from O'Reillys. (Father in law works there, so I get a discount)
I would like to order a flywheel (I want to keep the manual trans) for the engine as all of the available engines have flex-plates. I plan to order the 1982 6.2L flywheel for a 1/2 ton truck. (to match the 1982 6.2 engine)
I plan to keep my current NV3500 transmission. If it grenades, I will replace it with a NV4500 or possibly a 5600. I don't think this is an issue, as wiki says the NV3500 is rated for 300lb-ft of torque. Wiki also says the 6.2NA is rated at about 255lb-ft. So I plan to purchase a 12" clutch and pressure plate for a 1999 5.7L (gas) engine. 1999 manual trans gas V8's had a stronger NV3500 trans in them. The input shaft should still be a 1-1/8" 10 spline shaft.
The engine has a vacuum pump installed where a distributor would go on a gas motor, which I plan to use with my current brake booster. Do I need a vacuum canister?
I plan to use a push-button momentary switch on the dash to excite the glow plug relay. On cold days I plan to push the button, count to 8, release, and try to start the truck. I may install an ether kit and a block heater as well. (I live in Eastern IA, were it can be 0F for a week or so in the winter.)
I plan to remove the high pressure fuel pump and sending unit from the gas tank. I will replace this with some type of suction/pick up unit.
Any idea if I can keep my current guage cluster? I would really like to keep the tachometer. How will I hook this up?
I plan to run a 50 micron pre-filter with a water seperator. I plan to run a 6 micron final filter. (I can get a remote mount manifold through work.) I am not sure if I will use an electric lift pump or keep the mechanical pump.
How do I keep my cruise control?
Does this jive with what you guys think I can do? Just looking to keep my fuel economy (I get about 22mpg Hwy / 19mpg country roads now) Anything I am missing?
