    TBI to Vortec swap

    I have a 2x4 1999 donor, that I would like to take vortec from and put in my 1994 4x4
    Is that possible?
    What issues do I need to overcome?

    Not knowing how to do it would appear to be the biggest issue.

    So not questioning "Why?" The PCM has to be swapped, wire harness, and check on fuel pump pressure.

    I would not do this. Way too complicated to make all the computer controls and harness changes.

    Put an LS with a carb into an old jeep or Ford/Chevy for a play truck sure, but for a driver, I'd buy a GM service parts long block, and swap everything over to the new one. You'll be way ahead, cheaper, easier and for longer.

    Probably $2K, plug and play, warranty.
