Look at the fifth digit on a 1972 Camaro VIN (although the SS model was produced prior to 1972, it was not coded into the VIN until that year). The letter “K” stands for the base 350 SS engine. The letter “U” stands for the big-block SS engine. Any other letter in this spot indicates the car is not a SS model.
Look at the eighth digit on a Camaro VIN from 1996 to 2002. The letter “P” stands for the LT1 engine, which was used in the SS. The letter “G” from 1998 through 2002 stands for the LS1 engine used in the SS option.
Look at the fourth and fifth digits of a 2010 or 2011 Camaro VIN. The letters “F/J” stand for a SS automatic transmission, “F/K” stand for 2SS automatic transmission, “F/S” stands for the SS manual transmission and “F/T” stands for the 2SS manual transmission. Any other letter combination indicates the vehicle is not a SS.
