The suffix code (also called the "application" code) will be at the end of a string of letters and numbers (that's why it's called a suffix). The suffix string is usually a letter followed by a date code, followed by 1, 2 or 3 letter code. This is found in the area near the distributor, above the fuel pump. The suffix string of letters/numbers are always stamped in, not cast into the block like the date code or foundry ID code. | The suffix code (also called the "application" code) will be at the end of a string of letters and numbers (that's why it's called a suffix).

| − | There may also be a partial VIN number stamped in a separate string of numbers near the suffix string. If the block is missing the suffix and partial VIN, there's no way to know what the engine might have come in originally, unless there were other external clues like a carb w/a governor on it (would be on a heavy truck or bus), or if it had a large bellhousing and a HD "granny low" trans (also HD truck/bus application). If the crankshaft has a pilot bushing in it, that would mean it had been used w/an auto trans- although this could have been added later. | + | There may also be a partial VIN number stamped in a separate string of numbers near the suffix string.
