I'm looking to put a 4.0L in place of a miled out 2.9L....does anyone know what all has to be done?

start a thread outlining what you are doing at each step.it will be easier to give advise,good luck its a great swap.Awesome links.... I've decided to do the swap simply because my '91 2.9 5spd is starting to tick me off. I suspect a cracked head although there's no lack of performance to the engine, she's still pretty peppy running 34's. I smell fuel in the overflow tank as well as the bubbling in it when running and minor coolant loss from somewhere up near where the tranny and engine mate. I did a pressure test on the radiator with it running, and it dropped slowly, but held steady when not running.
Anyways, I found a running donor '91 exploder with new clutch in the 5spd, and offered the guy $500 for it, he came back with an offer of $650 but exploders are a dime a dozen around here so I'll see if he'll cave in to my offer. From what I've read this should be a fairly straight forward swap especially considering both trucks are the same vintage and have standard trannies.
Any last words of advice before I tear into the little byatch? (besides EVTM as I have access to all sorts of manuals at my friends garage)
