1966 396 V8 Engine Production

The base engine for the SS396 series for 1966 was the L35 396cid 325hp engine. This engine (along with the L34 and L78) was also an optional engine in the El Camino and 1,865 L35 engines were sold in the El Camino body style. There were 72,272 SS396 sport coupes (66,380) and convertibles (5,393) sold. There is no way to know how many of the base L35 engines were sold in SS396 sport coupes and/or convertibles. One can only take the number of L35 options known to be sold in the El Camino body style (1,865) and subtract that from the total number reported by Tonawanda and arrive at a number that would include Total L35 SS396 Chevelles and Service Engines.

One cannot take the number of L34 or L78 engines into account for SS396 sales only since these were also available in the El Camino and only a total number of L34 and L78 options are known; what body style they went into is not known. Since it cannot be determined how many L35 engines were sold in the base SS396 series (Total L35 Engines) and the number of L35 service engines cannot be determined.

L35 engines could be equipped with either a Rochester (or Carter equivalent) Quadrajet carburetor or Holley carburetor; all L34 and L78 engines were equipped with a Holley carburetor.
