This swap would involve using the LA O.D. bellhousing and an adapter plate from Gill Welding-
T-5 Bellhousing Adapter Plate For Slant Six | gillwelding
I know it says for slant 6, but the transmission patterns are the same.
This thread from the slant 6 forum details the process using a Ford T-5, so some of the parts may differ, but the process should remain the same. Again, it's for the slant, but the 273 would work the same way.
