Has anyone on here ever rebuilt and/or beefed up an I-6 4.9L? If so what did you do to it, what was the result, and were you happy with it? I have two trucks (both are 93 F-150's) with the I-6 (ones 2wd and the other is 4wd). I would like to take the one out of the 2wd and rebuild it giving it a little more power and torque so I can swap it out with the one that is in the 4wd to make a nice off road truck. Thanks.
