Would A 351 Cleveland Slide Right Into My 79

[Haxaw]

I can get a 351 C and I was wondering what would need altering to drop it in or if the heads are interchangeable as the motor has been sitting a while.
I have the 351 M and C6 tranny.

The 351C and 351M have different bolt pattern's for the tranny.

The heads should be able to be changed over. The internal componets are different and like Freak said the bell housing bolt pattern is different. You would better off putting a 400 or larger in it.
