Thread: 03 GM engine swap

  1. #1

    Default 03 GM engine swap

    My auto mechanic buddy has swapped a 5.4 in place of a 4.6. He did this in a pickup. Anyone ever try this in a Gran Marquis??

    It's been done a few times. That said, a stock 5.4 in place of a stock 4.6 is not worth the hassle. If you build it, then it might be worth the time.
