    Bob, The 1971 LT-1 Engine code is: CGZ. It was written upside down on the side of the block in a yellow grease pencil. This told the line workers working at Flint exactly what internals will go into the engine block. - Ron

          The engine suffix code written on any block (i.e. any horsepower or configuration) should be the same one that's on the stamp pad as well as on the sticker on the valve cover.

            Think they put the engine code there so they could get the right engine in the frame without having to look at the stamp pad.

              I think it was done to identify the block when going down the line at Flint or Tonawanda before the stamp or the suffix sticker ever went on the block, since it's under the paint.
              Only with age can we generally see it under the paint. St Louis and now Bowling Green look at the suffix sticker.

                Here's anblock CGZ crayon (2).jpg original. Rather faint--the "G" is in the center, the "C" is hard to see other than the bottom.
