Swapping Powerhouses
1) Now, I hate to say this, since I love my LT1 so much, but I'd say go with an LS1. Since, as I said, you're going to do a bunch of stuff ANYWAYS.
2) Get a t-boned LS1 FBody. You'll get all the major components you need. A motor, a tranny, a rear end (not sure if you need to ditch the V6 one), the wiring, the computer, the springs (you'll need them upfront, and they are diff in back anyhow), sway bars and the better gauge cluster. Thats just naming what comes to mind right away.
IF You don't want to do the LS1 route, I still say follow #2, but replace it with an LT1 FBody for all the same reasons.
Hope that helps, GL.
