LOOKING TO FIND OUT IF MY 66 GTO WOULD HAVE AN ENGINE SERIAL NUMBER TO MATCH THE VIN. IT HAS THE CORRECT XE CODE
Engine serial numbers were not 'matched' to GTO VIN until after 1967. The only real proof is the Protect-O-Plate (if you have it), which has the VIN and engine serial number on it. There are a few things you CAN do on your own to check, however. The XE engine is correct for a 4bbl California 389. Make sure the heads (casting should be "093") and manifolds are correct for the date of manufacture. If the casting and date numbers all fit, you have a "numbers-matching" car. Again, to know for sure if the engine is original to the car, you will need the POP or build sheet from PHS.
