Alright thanks for all the input everyone!

Zeus: I would primarily be driving on road but maybe occasionally a dirt road here and there. The reason I was sugguesting an LS1 primarily, is because I was planning on just getting the engine from a z28 camaro, they come pretty cheap found a few for around 5k so I might be able to get the engine, tranny, radiator and other parts needed for the swap all for 5k from the maro and after I strip all I need from it I could part the rest out and probably recoup a couple hundred dollars.

Ascinder: I have a friend who's father has a shop and does alot of strange work like engine swaps and aftermarket installations. I might give him a call and see what he might be able to do with it. I also have a shop around the airport here that works on the larger isuzu trucks and they were the place I took my vcross to, to find out what was wrong with the tranny and they seemed very knowledgeable and found out that I had a cracked head while they were looking at the tranny. they probably could do the swap but would probably be more expensive than my friends father haha.

Once again thanks all for the help and input!!!
