1969 El Camino Engine ID Codes
The engine identification code consists of the engine assembly plant, the engine assembly date, and a 2 or 3 letter suffix indicating the cubic inch displacement, the horsepower rating, and generally, what type of transmission was to be installed with the engine. Manual transmissions required a bushing in the rear of the bellhousing where an automatic transmission did not. Many engine "accessories" such as the carburetor, distributor, and exhaust manifolds were not installed at the engine assembly plant but rather at the final assembly plant.
During the 1969 model year, the 396-cubic inch engine was increased in size to 402 cubic inches by means of a .030 increase in cylinder bore size. It is believed this was done due to less restrictive emission standards on engines 400 cubic inches and larger. These new 402cid engines can be identified in 1969 by the three letter suffix code.

A total of 54,851 6-cyl engines were installed; 25,919 230cid and 29,932 250cid engines.
A total of 448,501 8-cyl engines were installed; 245,488 307cid, 116,383 327cid, and 86,630 396cid engines. This figure does not include the 323 427cid COPO engines. Since the 427cid COPO Chevelles were NOT built as SS396 optioned Chevelles, the 323 number would, logically, be subtracted from the base 307cid engine totals.
