Since this thread was brought back to life I have some questions that follow along the lines of the original title.
I understand the differences in the bell housing bolt pattern, that there were various updates along the way, and the gear ratios are the same.
When it comes to the internals, is there any difference between the big block, small block, or diesel variations? Could I physically build a small block version to the same specifications as a diesel version?
