you guys are a great help, i would appreciate any more comments or suggestions that you have... as far as lifting the body off the frame, i work at a garage and we have big 10 ton lifts, im pretty sure i could just let the body loose of the frame and pick the frame right off with a lift and it would leave the chassis sitting on the ground. I would rather just take out the front grill i think though. If im going to do a complete engine swap then i am REALLY going to need any extra tips or suggestions that you guys could possibly give me. The 5.4 is that the equivalent to like a 351? or what would that be in cubes? Is the 4.2 even worth leaving in the truck? I don't exactly want like 500 hp or anything like that. But i would like to be able to at least be respected for what i have accomplished. If there is any kind of market for a 4.2 I might be interested in that also. Lemme Know...
