So I got a 93' 3500 Cheyenne, 454 that I'm redoing for a high school project. Everything is stock on it, and it needs an engine rebuild. No I can't swap it or do anything overly expensive. However, I am wondering what I could do to get the most horsepower possible? It has a ton of miles so it will need to be bored over into a 468, and I'm wanting to make it a rolling beast, so anything to amp it up from what it already is now would be great. If its bored to a 468, is there any cam work/ swap or stroking to further improve it? If so, how much and also general price range?
