I traded a project car I lost interest in for a junk GMC pickup with a 5.3 a year or two ago. My intention was a new engine for my '94 C1500 stepside, which has a 305. The guy I got the truck from had a sweet, late 80's Cutlass 442 with a 6.0 swap. He was telling me how easy it was, but he works in a fabrication/hot rod shop, so we probably have different definitions of "easy." I also want to keep the manual trans, which looks like a pain in the ass with an auto trans donor. Anyway, two weeks ago, a guy drove by and saw the GMC sitting in the weeds off my parking lot, and made an offer more than I had in the whole shebang, so that ended that dilemma for the immediate future. The 305's got about 190K on it, but still runs great, doesn't smoke or burn oil or anything. I only drive it 1200 miles or so a summer. Just think it might be more fun with a bit more snap.
