Revision as of 23:40, 1 August 2016
The engine number is stamped on the engine block itself. It positively identifies the engine size (e.g. A12) as well as the serial number. The mark is always on the left (distributor) side of a Datsun A-series engine, but the location varies with the year. If you do not see the number, wipe the grease off the engine block.
