Gary Corns and his team are building a very unique 1939 Plymouth truck for Colorado Auto & Parts. What makes this truck so wild is the 757 ci (12.4 L) Jacobs R-755-A2 radial aircraft engine sitting between the front wheels. The air-cooled engine has seven cylinders and produces around 300 horsepower. The Jacobs Aircraft Engine Company produced these engines for several aircraft and this engine came from a Cessna 195. Besides the aircraft engine the truck has a aviation theme and includes features several components from airplanes in the interior.
