Most of the 383's I see build all their power higher in the RPM range than I'd like. They're great for a car or a muscle truck but not for a tow rig. The biggest reason of all is, I'm sort of a purist and the truck came with a 400 and I'd like to put a 400 back in it. The previous owner swapped in a clapped out 350 from an '85 K10 and I'd like to put an original engine back in. I'm not going to be racing or really flogging this engine too hard but I do need the cubes' to haul around firewood and my Jeep.
