Found:

727 from a 440 6bbl car built at the Hamtrack plant. Assembly/part# 3410672. It must have been a really late car going by the VIN.

The VIN is:
0B44034x (if you can fill in the last number and prove it, I believe I have your original trans)

This trans was rebuilt a few years ago through a very well know trans place. And this might have been someones "core".
