Matt, from what i have seen on the 912 registry the Vin shows manufactured year as 65 model year 66. I didnt see on the registry where to find the approximate month though.?

The Engine shows to be manufactured in 66 but falls under a 67 model year.

The Trans number on the registry I see as a 902/1 begins with 234001-238942, so i didnt even see the number of mine within that spectrum. However, another posts stated the trans number began with 221000-.....

So, could it be that this Karman built car in 65 labeled as a 66 production year been given the optional 5 speed 65 gearbox, and a 66 manufactured engine labeled as a 67?

These early cars have so much interesting history, its nice to learn the unique differences.

Thanks

As I previously stated, we know your gearbox was made the 18th week of 1965.

On the engine I would not be in the least bit surprised if it is not original to the car. 20 years ago when noone thought these cars were going to be collectible, keeping things numbers matching wasn't really considered important. As recently as 2005 when I was working for Carquip here in Boulder, we frequently would take in a core engine and sell them a rebuilt one that we already had on a shelf in the warehouse on an exchange basis. We were even doing it with 356s. Little did any of us know that the day would come where numbers matching would make a car 20-25% more valuable.

How can I verify if the engine is original to the car?

Also, Can you tell me more as to why I only see the one serial number on the engine and no other stampings.

Sorry, I'm a gearbox guy by trade. It is true that back then if you ordered a replacement engine it frequently wouldn't be fully stamped. When I worked at Carquip we had several 911 engine cases like that, though they were the other way around from your situation. They had type numbers on them, but no serial numbers.

The only way to find out (maybe) if it is numbers matching would be to pay for a COA from Porsche. Though that would only show how it was originally delivered and often things are missing. The COA on my 914 Bumble Bee shows my engine number but no gearbox serial number. And the older they get the more inconsistent they seem to be.

I don't know if you have closed the deal yet, but if it's a decent car, it is worth buying. A nice old 912 is a good car even if it may not be 100% original.

You are told things that you obvious do not want to hear. However, this is not going to change anything.

The 65 model year 912 was not started until the April of 65 and ended at the end of June of 65. The were only built about 3 months for the Euro market only. The 66 model year started in July of 65 and ended June of 66. Before you ask why it was started in April of 65 and not earlier. The Factory ended the 356 C in April of 65. There were no New 65 912 sold in the US until the 66 model year. Because of the 356 C still in production.

The engine is not original to this car the number is even later that my 66 that left the factory at the end June 66. The Serial number is only on the third member only. If you want to see the casting numbers on the other parts of the engine. Pull it and then remove the fan shroud they are under where the fan shroud covers.

The transaxel 902/1 was started being used for the 66 model year before 66 and for the 65 912. It was the 901/0 transaxel.

So the car in question is probably very early 66 model year. The transaxel is a 66 model year 5 peed most likely, because of the low serial number, original to the car. The engine has been replaced with one from the 67 model year.

Thanks for the in depth reply! and to all others who have helped along the way! You guys really know your porsche's and its nice to learn from all of you! SmileWavy
