Q: Engine Unit Number Does Not Match
The engine unit number stamped on my 1968 does not match the Billing History but I know it is an original engine. The engine code is WK, and the number next to that is 205848, engine unit production number per the Firebird page Tech info and has no reference to VIN number. Then the “engine unit number isted on the PHS Billing history is 205818. Note the number varies in one number: 4 vs 1. Could this be a miss stamp or some type of mistake.
A: Engine Unit Number is the number stamped on the fron of the Block next to the Engine Code. Also found on the Billing History. These numbers should be the same. The Engine Unit Number and partial VIN were stamped on manually and were not as deep as the Code stamp. Also, there was not alot of quality assurance & certification back in 1968.
The Gang-Stamp Tool could have slipped during the strike causing a partial stamp. Wouldn’t doubt that a mis-stamp could have happened either. Considering the numbers you shared are so close, seems obvious they are one in the same… despite their seemingly different appearance. I wouldn’t lose any sleep over it. Who would believe that you had the wrong engine and it just happened to be 30 units different from the original ?
A: My guess is that the digit “4 ” is correct and that the digit”1″ stamped into your block is a weak stamping of the number “4”.Ive seen several weak stampings of production #s and VIN #s Some of which appeared to even skip a digit. This was actually a very weak stamping and had only a small portion of the number visable. Take a real close look, Im betting its a 4.
