Personally, I hate diesel swaps. They're stupidly expensive since you'll have to beef up the entire drivetrain/axles, they're usually only slightly better on gas, and people who have them choke themselves and everyone else on the trail with diesel exhaust. Everything you get from a diesel you get in a SBC swap, and that's orders of magnitude cheaper. That being said, this should have all the info you need:

thanks for the advise, and the link. i am ready to beef the whole drivetrain up to make it all suitable. the 4bt doesnt make that much more power or torque its just where it makes it in the rpm curve.
