First race of the season. Riverside Int'l Raceway. Between the dogleg and T9 @ about 8100 RPM. Blew holes in both sides of the block, cut the oil pan in half, I spun in my own oil and backed 'er into the boilerplate wall still going Goodness Gracious fast. Shortened the car about three feet. The sudden stop jerked the engine off the mounts and punched the starter motor armature and bendix out through the cast aluminium end plate and it rolled down the banking. A thoughtful corner worker tossed it back into the seat.
