    your biggest issue will be with the flywheel. The 302 is a 50 oz imbalance, the 351 is a 28 oz imbalance. I have done this before, put a 351 in a 91 Bronco.
    AODE will bolt up. Just make sure you have the right flywheel. The 302 flywheel will bolt up to your 351, but it will shake like all hell.
