Many thanks for this great information!
I got curios about the difference between the T10-B (mentioned by John) and the T10-H (I own) main cases. I found an interesting pdf on the internet which contains some information I’m not able to verify/confirm.
Ford T10s used two iron main case configurations and both main cases are 9 1/2 inches long. The early, narrow transmission mounting bolt pattern T10 B-1 case was used from 1960-64 with 221/260/289 engines that had 5 bolt blocks and the later T10 H-1 case with a dual mounting bolt pattern entered service in late 1964 for use with the 289 and later engines with a 6 bolt block
