a well tuned t-quad would work well with that combination.
the factory torque converter for the pushbutton transmission [727, correct ?] will work good as well.
just my opinion. your mileage will vary.
I've never messed with a T-quad, so excuse the dumb question, but why would it be better than say a Holley?
I should add that I have upgraded the input shaft and support on the 727 so I can run the later torque converters. Not much of a selection for the early style input shaft.
The body is still at the hot rod shop getting painted but should be ready to come home soon. I've still got a long way to go, but making progress.
