Keeping a v8 cool in those things is not hard as long as you are willing to buy a good radiator. I would also recommend doing an electric fan as well. Anyhow, the v8 swap is very much like the swap for the 4.3, and you are going to want to spend some money on a good radiator if you do that still anyhow.
I guess that the truck being a turtle would depend on your definition of a turtle hehe. When I had my trucks, I found that a weber carb and header were all the power I could ever need. Don't get me wrong, it wasn't a speed demon or anything, but the power was there and I had the known reliability of it being a toyota engine. And the 20r is more than capable of giving you enough power to do whatever you might want to do offroad as well. Anyways, you could also check Northwest Offroad Specialties and Downey as well for some other 4x4 performance options. Good luck.
