Tatum Special

With his success in 1953, Chuck Tatum was able to secure sponsorship for an engine from Wayne Engineering, manufacturers of speed equipment for six cylinder Chevrolet and GMC engines. For the 1954 season, Wayne sent Chuck a new GMC engine fitted with their famous Wayne 12-Port Cross Flow cylinder head. The ignition system was still Mallory, but the carburetion was changed to three Zenith 2-throat side draft carburetors from a GMC fire truck. The new engine produced considerably more power than the 1953 engine that used a modified truck cylinder head. Chuck took the car to the Bonneville Salt Flats where he drove the car to a top speed of 157 mph. At the end of the 1954 season, the Wayne Engine was sent back to the Wayne Factory for overhaul. When the engine was returned to Chuck in early 1955, the Zenith carburetors had been replaced with Weber Side Draft carburetors. During the 1955 season, while the car was being worked on in a Palo Alto garage, the Wayne engine was stolen and never recovered. Chuck finished the rest of the ’55 season with a borrowed Ford “Flat Head” V-8 engine.
