Lancia numbering systems are a study in themselves. Consider the numbers on the Aurelia engine – the motor number is stamped on the block – sequentialLY (to motor production, not cars). Sometimes one finds an \u201cA\u201d stamped on the B24 block for Spider America, with its detuned, torquey cam. Matching the motor number to the car remains an arcane bit of Lancia knowledge only found after decades of experience.<\/p>\n<\/p>\n
The numbers on the head are most fun. There are several, and include:<\/p>\n<\/p>\n
casting number – B-1101A, for example<\/p>\n
date of manufacture (Jan-53) small stamping<\/p>\n
series number (roman numeral I-VI, not sure if this conforms to the series of the car….)<\/p>\n
motor number (stamped on the ends)<\/p>\n
The oddities are also the amusing part – Steve Katzman has sent in pictures of a B24 block with the number written on the block, in blue pencil (shown above). Never seen that before. He also found an \u201cA\u201d written on the firewall, although the shot isn\u2019t exactly conclusive….<\/p>\n
Inside the engine, many parts are stamped or have numbers cast in. The radiator Y is most notorious, listing B20 or B24, or even Nardi\u2019s name when he cast them. I think these are consistent, but there may be variations in them as well.<\/p>\n
Major machined parts are stamped: conrods are matched and stamped to each other and to the motor, as are main bearing caps. Water pumps have model numbers cast in their casing, but since the pump could be used in different models, a visit to the parts book is required to determine the right one for the motor.<\/p>\n
The historian looks for dates along with the stamps – and the heads are one of the best places to look. The engine blocks came in a number of different castings (last count was 6 different ones), anyone know if they are stamped anywhere?<\/p>\n
