Among the wild and crazy efforts of the day, few rival Ohio George Montgomery's twin turbo Boss 429 AA/GS racer. The Mr. Gasket Gasser initially debuted with a blown Cammer, but by 1971 had switched to the turbo Boss. The class required a full frame, and Montgomery utilized one from a Willys with a fiberglass Mustang body as requested by Ford-thus the decidedly non-stock look. The car's quiet turbo nature and class dominance caused the NHRA to eventually saddle the car with a 0.50-second index, and then in 1975, the rulebook outlawed the turbos. Montgomery's car typically ran mid 8s in the quarter at nearly 170 mph, making for one heck of a show. Regarding the Boss 429 as a drag race motor, Montgomery says "I don't know that it was ever a very good normally aspirated drag motor, but it sure did love boost. We dyno'd it at Sonny Meyer's shop in the early '70s, and it was making 1,800 horsepower." (George Montgomery photo collection) View Related Article
