Need help on selecting stall torque converter

Dany and I just put our first "stall" converter in our '66 Cuda.
After having all the questions you have, and understanding how important it is I called Turbo Action and they built us one.
They will want to know EVERYTHING about your vehicle.
and it intended use.
Like with a cam choice, be brutally honest with them (and yourself).
In our case, a bracket car mostly but, drives an hour one way on the interstate at 70mph to the track.
We were shocked at how much harder it launched at WOT, yet driving around town or on the interstate at part throttle it seems totally stock!!
Might be right up there with cam choice as far as HP per dollar.
( it was $600 and a 2 week wait BTW)
