help with 273

Um, yeah about that 3 speed.

The original 3 speed behind a 273 would have been an A-745 gearbox.

This is an old, simple unit with a non-synchromesh 1st gear. Ratios should be 3.02:1 / 1.76:1 / 1:1

Not the nicest gearbox to drive by today's standards. A complete & careful rebush / rebuild of the shifting linkage would be necessary. An aftermarket floor shifter would probably be a lot easier to deal with.

To each his own, but I think that would be less than fun to drive. A 727 has 3 speeds, and with the right valve body you can slap it around like an M/T.
