Beefing up a 727 trans!

Looks like a nice kit that Dusterb318 mentions. All parts appear to be from A&A, a well known supplier for tranny parts. At a minimum, I would suggest the kit with the billet steel drum for your application. The aluminum drum I mentioned would wear faster than the steel drum but may be worth a .10 second (or less) in the quarter due to less reciprocating weight.
