I was wondering what i would have to do in order to get this swap. I know motor mounts. I already have the 5.7 vortec. I heard you just swap motors and all the wiring is the same. I also have the 5.7 pcm. Is all this plug and play? Just take out 4.3 and swap in the 5.7 motor and computer? If there is a wright up point me that way or if anyone has done it could give me some pointers. I have a 98 Cheyenne fyi.
