I have a '65 truck X block Chevy 409 for sale. The short block was rebuilt and assembled several years ago . I have all the receipts for the motor . The heads are the 425 HP heads also rebuilt and fresh. The motor comes with the correct two 4 barrel manifold and carburetor's. The short block is assembled but the rest of the motor is only mocked up together for photos . Any questions needed answered please feel free to message.
