If you can look at the front of the block, the engine information should be there. Usually on the passenger's side of the engine just below the cylinder head. Unless it's a '60s vintage Cadillac motor. Then the complete vehicle identification number (8 characters) will be stamped on the top center of the motor just behind the intake manifold. Let us know what you find out. We may be able to decode it for you. I have a '67 Chevrolet Factory Shop Manual. HTH. - Jim
