The "Illegal" Missing Gear That Broke The NHRA: Chrysler's Banned 2-Speed Secret?
The "Illegal" Missing Gear That Broke The NHRA: Chrysler's Banned 2-Speed Secret? How did one California drag racer completely outsmart millions of dollars in Chrysler engineering simply by throwing parts in the trash? In 1971, the NHRA Super Stock class was the ultimate battleground for American muscle cars. If you wanted to win, you had to follow the strict factory rulebook. But one legendary Mopar racer realized that the ultimate performance upgrade wasn't an addition—it was a brutal subtraction. By exploiting a massive loophole in the NHRA rulebook, he turned the legendary Chrysler A727 TorqueFlite transmission into a violent, two-speed mechanical monster that shaved massive time off his quarter-mile runs. Detroit engineers tested it to destruction. Track officials were completely baffled. And the NHRA was eventually forced to rewrite their entire rulebook just to stop it. This is the unbelievable true story of the "missing gear" trick, the brutal mechanics behind it, and why this banned racing modification is still talked about in drag racing history over 50 years later.
