In 1966, the engine builders of note precipitated a “trick tire” war between Goodyear and M&H. Goodyear conducted tests at Riverside and selected The Surfers because of the bulletproof consistency of their fueler. During the four-day test, the boys put 26 banzai passes on their low-buck 392 and lost only a rearend in the process. Petersen’s Bob D’Olivo mounted a motor drive Nikon on the front of their 6-71 supercharger to record the action. Note the lack of visible oil vapor from the breathers and how the 200-plus-mph wind nearly blows the helmet off Sorokin’s noggin.
