I would think they would be the same, 302 and 351s are the same block if im not mistakin, they only problem you might have is if your truck has a C6 and other one has an AOD youd have to either put a floorshift in it or change your column shifter to the AOD. and if that 96 has an E4OD i wouldnt even know how to begin to make that trans work right.
