1966 GTO Numbers Match
Hi,
I am in the process of buying a beautiful restored 1966 GTO post. The seller states you cannot number match the motor to a specific vin # or data plate for 1966. He states you can match it to the year but not the car. I have asked the local buffs here in South Florida and they say otherwise. Please help as I am ready to buy this baby and I just want to be sure...The car has a year correct 389 and the original 2 speed powerglide. Thanks to all ! |

He has the PHS Docs on the car. They show the 389 with the Carter 4 barrel. They also state the auto 2 speed and the 323 rear end. But no motor number to the vin.

Everyone I talked to said that 1966 was the last year for Pontiac not to have a vin stamped on the front of the engine.
I would check the date code cast in the block back by the dist. hole and compare to the invoice date of the vehicle. Other's here will help with greater detail,

Even the 67 engines didn't have any numbers associated with the VIN. There is a sequence number stamped below the code. That number also is shown on the the PHS documents. The engine should be stamped YS, unless it was destined for California, in which case it would have been and XE coded block. (4-bbl w/ a Powerglide)

Unfortunately, the Engine Sequence Number does not appear on the PHS Document, also known as the Pontiac Billing History for 1966. It does in the center of the document in 1967 and that is where the confusion comes in.
There is only three places you will find the Engine Sequence Number for a 1966 Pontiac: 1) On the passenger side of front of the block just under the head 2) On the Factory Build Sheet.This is a different document from the PHS Billing History. This was the sheet that the assembly line workers used to build the cars as they came down the line. On early Pontiacs, it is EXTREMELY rare to find the Build Sheet with the car. If it's not with the car, it is gone forever. Pontiac did not keep records of these, only the PHS Billing History. 3) On the Protect-O-Plate (POP), which was with the owners manual in the Glove Compartment and usually is long gone. The Factory Build Sheet and the POP are the only two pieces of docementation that show both the VIN and the Engine Sequence Number for 1966 Pontiacs. It can be different for other years, but that's the story for 1966. Jim

I have seen very few build sheets that include the Engine Unit Number on the form. There is a box for this information, but the number is not usually printed.
The VIN was stamped on the blocks begining with the 1968 model year, which started in late August of 1967. There has always been some confusion concerning the 1967 or 1968 stamping. It was both; late '67 calendar year which included the 1968 model year. |

Protecto Plate is the only way to know the number matches the car.
