For my situation, my jeep will get a 4" lift springover. Ask whomever you talk to when you buy your lift if it will hold up to a heavy V-8 conversion. You have to add some lift to clear the oil pan. I am going to use an aluminum radiator, but there is going to some math involved. Instead of having an entire chevy truck front end to play with width wise, you're going to be down to half the space. I'm going to make mine identical to the stock, but deeper. at least a four core set up. If you get the right amount of radiator, I wouldn't think you would have to go with a high flow pump, but that is more personal preference. Electric fans are a must. Engine driven fans are a dinosaur idea that has had it's time. Why waste gas on them? A nice thing that I have been finding out is that the advance adapter Chevy 350 motor mount conversion kit works with the 6.2L. Depending on what you plan on for a drive train, will tell you how much engine bay clearance front to back you'll have. There is plenty of room. Go slow, and make sure you get a radiator and some fans to mock up with your motor with all the accessories. finding out that you blew $400 on a custom radiator that you can't use blows big time.
