my dad bought a 1956 Ford Customline Victoria with a bored and stroked 312 with G heads, E4 cam, etc. It had Ford's 2 four ballel intake and the teapots. He bought the car off the Chrylser (not a misprint) showroom floor in 1969 in Mt Airy, NC. There was a good reason that car was on the showroom floor. Nothing in town could touch it. SCARY fast, he said, and so have all of the old timers I have talked to around town. Dad said the only trouble he had was keeping them in "tune", but he said a local mechanic would always "tinker" with them whenever dad pulled in and then the things would smoke the tires. He burnt out 3 Ford rear ends (didn't have the nine inch), tore up a couple of transmissions, the usual. Come to find out, the car was moonshiner's vehicle he had traded in for a new MOPAR....
Unfortunately, the car was rear ended by a drunk on Christmas Eve. The 56 was parked at the time, and the driver hit it so hard that the frame was bent and it was pretty much a total loss according to the insurance company. Dad traded the car for a piece of land (about 3 acres) and the buyer parked it on one of his farms. Where the car is today, who knows....
