In 1960, my 1939 Ford coupe was drag racing at George Field, Lawrenceville, Illinois with an Oldsmobile 303 engine, turning 106 in a quarter mile . My high school buddy bought the car in Robinson, Illinois in 1962 for $350.00, still running with the 303 Oldsmobile engine. He sold the car and as time elapsed the Olds was pulled and a hopped up flathead was installed. I found the car years later and cleaned it up, still with the flathead engine in it. I have since found a complete Fenton adopter kit to reinstall the Oldsmobile engine back into the 39 and a nice 303 Oldsmobile engine (pictured with car). The big question, should I reinstall the Olds complete with NOS Fenton cast exhaust manifolds or leave the Flattie in? Oh, in addition this car may have raced at George Field in 1955 at the national drag races with the Olds. I am researching now.
