    i think its the wiring and the vortec gives out more power and theres more mods u can do to it.. its also easier to find performance parts for those

    its too much hassle to go from tbi to vortec. all the electronic wiring is different inside the cab, the engine harness is also different, and the external wiring harness is also different. plus none of it will bolt up and be good to go. u have to change out ALOT. u might as well go carb and drop all the electronic stuff

    its a bunch of stuff computer, harness, vortec engine, etc..... Your best bet is swap it out with a 6.0 or any lsx gen 3 or better.

    OR CARB like mention above, one other option is do the TPI and i want to say you can still use the same engine and they even make a tune port injection for vortec heads as well. carb will be the cheapest.
