This California Drag Racer OUTSMARTED Chrysler With a "Banned" Hemi Oiling Trick That Made 800 HP

What if the secret to making 800 horsepower from a 426 Hemi wasn't bigger valves or wild camshafts, but hidden drill holes that no tech inspector could find? In this video, we uncover the incredible story of how Sox & Martin Racing discovered a critical flaw in Chrysler's legendary 426 Hemi engine and developed an "invisible" modification that dominated NHRA Super Stock racing in the late 1960s. By strategically enlarging internal oil passages that couldn't be detected during inspection, they unlocked the ability to rev their engines to 9,000 RPM while competitors were destroying their motors at 8,000. This ingenious oiling system modification allowed them to extract an unprecedented 820 horsepower from a naturally aspirated engine using 1960s technology, revolutionizing drag racing and forcing rule changes that still impact the sport today. #dragracing #musclecar #hemi #racing #automotive
