I lived in Vegas in the early 60's, Got my first license there in 63. I don't remember what year (early 60's). The gaming commission ran chains and locks through the door handles into the Silver Slipper Casino for failure to pay a winner.
This is how we would sneak into drive-in movies before they got smart and charged by the carload, not individual.
This is one of the very few 24 cylinder Allison engines, 3420 cubic inches. After World War II, many kinds of military airplane engines were readily available at a bargain, but this was special. It was an experimental design built by General Motors, a Frankensteinian jam-up of a two Allison V-1710 12-cylinder engines with a common crankcase. The 12-cylinder, water-cooled engine had been used in American fighter aircraft such as the Curtis P-40 Warhawk, the Lockheed P-38 Lightning, and the initial versions of the North American P-51 Mustang. The V-3240 engine was installed in Henry J. Kaiser's Unlimited Hydroplane in the middle 1950's... Here is a photo of Henry taking the hydro out for testing at Lake Tahoe. The V-3240 engines were rated somewhere between 2,300 and 2,600 horsepower. I seem to remember that the one in Scooter Too was putting out about 2,800 HP. The biggest issue with Scooter Too was the weight. The engine was pretty heavy and the boat never got through the turns that well due to the added engine weight...
setting up the finale for vanishing point. if you watch it, note how they change the mopar out, and slam a base model camaro into the dozer.
