came from one of the links provided by a helpful member. The word SHOULD scares me.

The bell housing on these transmissions comes off, so the same trans could easily be on both 289 and or 352.

I am down to figuring out if it has a 9 7/8" case, or a 10 1/4" case. I will figure this out, and put it on this post for the next dummy like me.

Thank you guys for all of the help.
