Several local guys have had 727 trans explosions.

Dan Smith/ Qwkmopardan had one about 5 years ago.
He had always figured that the upgraded sprag was enough, until he had one blow up on the starting line and break his foot and put trans pieces in the windshield.

Now every trans he builds for anyone gets a billet steel drum if they are seriously racing the car.

In 2019 Cole Heilman has one blow up and broke toes on his right foot.

The billet steel drum is expensive, but so is a broken foot and it could be much worse than just a broken foot.
