Hannlusms,

The casting number you gave can be either a 302 (not likely), 327 or 350. Because of it being a 1967, I would suggest possibly a 327. This was an excellent, very dependable engine. If we can be of further help, please don't hesitate.
A little more info: The 1967 was the last year for the small bearing crankshaft journal. In 1968 the size of the bearing increased and remained the same size until present day. It does not mean that the engine was lesser quality because of the smaller journal crank.
