RE: engine swap
The hood is the real issue. I'd to a 5.4L mod motor if I was going big.

RE: engine swap
You'll need the motor, ECU, fuel system, new front suspension, new front brakes, stronger K member, tranny, driveshaft, astronger rear axle and new gauge cluster.
Total cost is roughly one arm and one leg.

RE: engine swap
Nope, the 4.2L (or a 4.3L if you go that route) is a direct swap. No other changes needed.

RE: engine swap

RE: engine swap
Yep, it's the easiest swap that the V6 owner's can do.

RE: engine swap
don't you need to get it tuned, really badly, once you do that because the timing way off and the fuel ratio is really lean?
