273, the good points

I believe the 8 3/4 could be found behind some of the later 1965 273's, including the 2bbl, 4 speed cars, but it was a optional.
I have seen factory 4 speeds with the 7 1/4 and have been told they started adding the 8 3/4 later in the production run because of the weakness of the 7 1/4.

My April build date of my 273 2 barrel 4 speed car still has the 7.25. I parted out a 65 Dart GT 273/235 motor with a 4 speed and it had an 8.75 with 3.23 open in it. Build date of the Dart was Jul23, 65 (really late build date) and the 8.75 was dated something like 3 weeks before the build date of the car.
