Beefing up a 727 trans!

This is why I advocate a billet steel front drum and bolt in clutch for anything over 400 hp!

The billet steel or aluminum drum is a good idea, most bolt in sprags aren't any stronger than originals, they were designed as a service part to save the case if possible.

Otherwise having said that there are a few rules one should always follow when racing a TorqueFlite.

1. Never do a 1st gear burnout. Start in 2nd and shift to 3rd. If you absolutely have to start in 1st then shift immediately into 2nd then 3rd.

2. If you break any driveline part, u joint, driveshaft, ring and pinion, axle shaft, whatever, always remove the trans and inspect/replace the overrunning clutch.

3. Install a good SFI approved aluminum or steel trans shield or SFI approved ballistic blanket. Do not use the carbon fiber ones.

I'm not real keen on the low band apply valve bodies because they can mask a problem and some of the trans brake v/b's have a timed release of the l/r band which can shock the sprag at speed.

As always YMMV don't take my opinion for gospel, it's just that, my opinion.
