Beefing up a 727 trans!

TCI sells a reverse pattern valve body but I'm not sure if it has the low/reverse band apply that would be necessary in your application.

Try to find front and rear clutch retainers that can handle five friction disks or TCI has a specially cut pressure plate and steels that allow you to use the five disks.

Get a high quality bolt in overunning clutch with extra rollers.

Consider an aluminum front drum, these are really pricey, but how much are your feet and ankles worth?

Don't forget red lined bands, front and rear. If this is a strip only application, you can go with the Kevlar bands, but Kevlar is too abrasive for the street.

Chris Andrews of Andrews Racing Transmissions should be able to help you with all these parts and I know they have a really high quality bolt in clutch. He's been super helpful for me with my 727 build and I highly recommend him. None of these parts will be cheap but Chysler never intended their 727s to be behind 700hp. Tell him Joe sent you from A-Bodies only.

Good Luck!
