You are talking about the 4.3L V-8 which will require all kinds of modifications to the steering, brakes, electrical, mounts, a capable cooling system and on top of that, you'll need a stand alone computer to run all of that. Sounds like fun, I wish I had the cash to do one like that, but I would hold out for the 5.7L myself,
