Hey guys! I had a 350 in my 89 that was knocking pretty bad due to worn out bearings, so I just recently pulled it out, so I am looking for a new a new engine so I can either start driving the truck again, or sell it. However, a buddy of mine just came across a 6.2 / 700r4 / 208 powered truck that he is considering purchasing for 4x4 parts, and is willing to sell the diesel engine to me. I'm very tempted to pick it up, and run diesel in the truck, both for the milage, and the potential for bio-diesel in the future. I know the engine will physically bolt straight into the old 350 mounts, that I will have to clean the fuel tank out for filling it with diesel, run the new lines, and other various smaller things, but what else will I have trouble with?
