All engine unit numbers
started with 0001001 and increased numerically as engines were produced. All
6- and 8-cylinder engines were numbered separately.
Only
two engine plants were producing engines at that time. They were the Flint,
Michigan, and the Tonawanda, New York, plants. All Corvettes that were equipped
with small blocks used only Flint built engines. No Corvette will have a Tonawanda
engine in this time period. After the engine unit number, a letter "F" or
"T" will appear to designate either the Flint, Michigan (F) or Tonawanda,
New York (T) plant. The next two numbers will represent the model year
