We just installed an A and A Torqueflite in our Road Runner. There is quite a difference between my home built torqueflite with a Turbo Action transbrake and the transmission from A and A. The A and A has all the best internals. The A and A is more positive in all gears. The transbrake is more positive when it engages and most importantly, the car is quicker with no other changes. If you haven't talked to Rick Allison, you should. He knows what he is doing. As an aside, my son and I went and saw Rick's facility. It is one of the most impressive shops I have ever been in.
Rick,
My trans was built by Chuck Lofgren, who has been building Torqueflites for racers for 40 years? He put all the needed upgrades in this trans, for my power level at the time. The next step only requires tougher shafts.
