1978 351M engine swap?

Question

there is also a c6 automatic transmission that goes to it, could they fit in a 1978 mustang with little modifications? if so, what modifications would need to be made?

Answer 1

check it 3 times because I don't think that wide of a motor fits and a C-6 is definitely too big to fit in that trans tunnel,a C-4 is a close fit and a 302W is also a close fit under the frame rails

Answer 2

pos a stronger diff but mostly minimal changes def a larger core radiator  

Answer 3

these engines were available 4 this model so with correct brackets would be straight bolt up.
