I have a 1988 F-250 4x4 with a 460 & a C6 automatic transmission. I also have a 1992 F-250 that has a 351M engine. Will the C6 in the 1988 bolt up to the 351M engine? Same bolt pattern? What I want to do is remove the 460 from the 4x4, and put the 351M in it's place. Any idea's, suggestions? Thanks.
