I’ll just paste the owner’s description here:
1966 Chevrolet corvette 427-425 hp 4 speed has both tops, motor and transmission have been professionally rebuilt.This is a unrestored car, and could be the original paint.It is believed to be a no hit body with bonding strips in place. The engine block is a 942, the heads are 3873858. The motor is not original to the car but it is a period correct 427-425 1966 corvette motor. This is a true 427 big block car. There is no rust on the car anywhere, it does have a split in the drivers seat.

No mention of any documentation? If it’s a real 427 Corvette, this may be with looking into... especially if that turns out to be the original factory paint.
