The vehicle identification number (car serial number) is on a plate welded to the body on the left front door hinge pillar. The first digit of the number indicates the series: 4 for Series 40, 5 for Series 50, 6 for Series 60, and 7 for Series 70. Next is a letter designating year (C for ’56, D for ’57, E for ’58).

The remaining group of six digits is the individual car serial number.

This number is also stamped on the top surface of the crankcase, just forward of the valve lifter cover on the left side, and constitutes the legal engine number.

Toward the right side on this same surface will appear the production code number, (stamped upside-down from the front of the engine) this number, along with the vehicle identification number (car serial number) will be used to identify the engine on product reports etc. The production code number does not constitute a legal engine number for registrations, titles, etc. A stamped letter X before the production code number indicates a 60-50-70-700 series engine equipped with 9.5 to 1 compression ratio pistons. A 1/4″ long dash (-) after the production code number indicates a .010″ oversize cylinder bore engine.
