Engine, Transmission, and Rear Differential all from different cars. The engine is a 69 383 that was pulled from a 1970 Roadrunner, but based on casting date and stampings it clearly came from a 69. The original 383 is in Florida somewhere as the car left Ohio with it, spent a few years there but came back with a 440, that was blown/frozen. So this is at least the 3rd car this motor is in. The 727 torque flight came out of a 70 Coronet, and the diff is the correct 8 3/4 banjo but when pulled apart the stampings on the gears were from and A-body.
