Those with blowproof bellhousings

Back in the mid to late 60's, Stock Eliminator wasn't required to have a clutch can. We were at a now defunct drag strip in East Texas and a guy pulled to the lanes on a 55 Chevy 2 door wagon to do his burn out. Just as he began to roll out of the box, the clutch assembly exploded. It decimated the floor board of the car and a piece of the flywheel bounced over and hit on of the track crew on the neck, severing his jugular vein and carotid artery. He went down and bled out so quick, no one had any time to react.
