probably will let him drive the V6 for a couple years and just start collecting the LT1 stuff

As much as I am a fan of LT1s, I think it would be far easier and cheaper to put in a gen 1 carbed small block and just build it up. More power could be had for less money. It would also be a ton easier to wire up. Just my .02$

If you really want to go the LT1 route, the easiest route would be to find a complete motor and tranny, along with it's accompanying PCM and wiring harness. You would also need custom motor mounts, some LT1 cooling system parts, and many other things I cant think of right now.

I would suggest checking with local junkyards and getting a complete setup from a firebird, camaro or caprice.

You could more than likely get the engine tranny for around $1000.
