Ok, for those on here who talk to me or read my posts on a fairly regular basis, I'm planning an engine swap for my 93 Burb. The 350 TBI is just too much of a dog with too narrow of a power band for my tastes. I was originally planning to do a 383 Tuned Port swap. In terms of difficulty, the TPI isn't too bad. Biggest issue would be the higher pressure fuel pump. Everything else would be pretty straight forward. So while I was bored at work the other night I got a wild idea of swapping in a 6.0L drivetrain from a newer truck (since at that point I wouldn't be able to use my existing transmission). The more I think about it, the more appealing it sounds. It would be more expensive, I'd have to wait longer to do it, and I'd have to push my next project a little farther into the future, but there would be a lot more upward potential than with the TPI motor. The 383 would probably have more power out of the box due to the plans for how I'm going to build it, but again, not as much potential beyond that. Figured I'd gather some input from the guys on here and just see what everyone's thoughts are on the subject.
