4.2 upgrade
[updated:LAST EDITED ON 20-Feb-02 AT 12:08 PM (EST)]If a 5.0 will fit, a 4.2 certainly will! And, whether swapping a 3.8, 4.0, 4.2, or 5.0, you're looking at basically the same amount of work (engine plus all the engine wiring and computer.)
BUT if you already have a V6, you won't be REQUIRED to swap trannies. If you have a 4-banger, you're looking at swapping just about everything between the radiator to the driveshaft.

I would check first. The 302 5.0L (closer to a 4.9L, actually!) has a different shaped block, obviously than the 4.2. If I'm not mistaken, the 302 is a shortblack small block V8, where as the set up of the 4.2 is longer but narrower. I could be wrong, but I would definately check it out first.
