The 4x4 frame is so different that I cannot tell if you'd have to notch or not. THe best way is to just drop it in there and see what you have for clearance. You may not have to do anything. For accessories, post up on LS1tech, Corvetteforum, LS1GTO, Performancetrucks.net and anywhere else you can think of for them. I think the Vette accessories would be best, then the truck and finally the fbody. I reserve the Fbody for last only because the alternator is next to the steering box. If you get it up high it makes for an easier conversion. I did fbody on my 93 and 92. It works fine but it's tight. The high mount alternator will allow you to move the engine fwd or backward as needed to bolt to the stock transmission location.
