    I have a 2007 (Classic) body reg cab short bed and I am thinking about pulling the 4.3 v6 out and putting in a 5.3 or a 5.7 v8 motor.
    Has anyone done this or do they all do the carb motors.
    Just looking for info for the future.

    thanks ran

    Everything you shall need. Its alot of work compared to swapping v8-v8, but well, WELL worth it.

    the 5.3 is the best swap you could do IMO. and you can run a carb easily as well. they are available on the cheap to so you get good power on a budget...
