Well not that I'm aware of but they might be different, one way to tell is to call your local Ford dealship's parts counter and see if the part number is the same for the 2 gearsets. I would think the blocks would be very similar but then again Ford has been known to change things around a bit. Pre 85 blocks had no provisions for roller hydralic lifters hold downs and they went to fuel injection in 87 so depending on how old your 351 block is there maybe a difference in the thrust plate area.
I'll keep digging around and see what I can come up with, Charles
