hey i got a 302 out of a 87 bronco fullsize that i blew. i want to put a 351m i got out of either a 77 or 78 t-bird in . i was told that if the intakes had the same bolt pattern and would swap, that i could just make the 351 work as fuel injected with few modifications. does any body know if that would really work? will it bolt up? if so would it be better than just leaving the carb on?or even worth the work? if i leave the carb then i got a lot of wireing shit to **** with, and im not exactly too good at that. and i didnt want to be all summer puting it back togather. that mud hole at the river is already caling my name? and also will the 4x4 c-6 tranny even bolt up? can any body help me out? i would really appreciate it! thanks guys

The tranny will bolt up with little effort, but your 302 EFI gear won't fit, as the 351M is wider across the heads. I have heard of guys trying this on 351C's, but the 'M' is actually a 400C block, which has a taller deck height, hence wider across the top. Therefore, stay with your carby setup, or buy another 302/5.0 from the wreckers.
