Need help with engine number please!
 

Hi all,

Purchasing a 911 and I have a CoA that lists the engine number as 620522 but the engine in the car is "6210270"

I know CoA's are notorious for mistakes but if the engine in the car is indeed original what do you do about a CoA that is non-matching? Have they ever been know to correct them?

TIA

You don't give much information to work with. COA lists a 1970 engine, you have a 1971 engine. Need the year of the car.

Looks you typo'd the COA engine number as it is short one digit. As E Sully posted, we need to know the year of the car because you have a 70 engine listed on the COA and a 71 actually in the car. Assuming from your post the car is a 1970, then it is doubtful, IMO, that the COA would be incorrect to the degree that a 71 engine was put into a 70 vehicle. To my knowledge (which is certainly not extensive in this area) Porsche never put a later model year engine into a vehicle at the factory.

If the car is a 71, and you copied the shortened engine number correctly from the COA, then it is quite possible a mistake was made as the number is non-existent.

If the car is a 70, most likely the engine was replaced by a PO sometime in the life of the car. If the car is a 71, it's possible the COA is wrong.
