Great.
Thanks!

I just got this engine:

6420081

Could not find any info about it

Thanks,

6420081 is a 914 engine from 1972. Your engine number is stamped on the top of the engine case and not on the vertical alternator base, correct? The information would be the same as a 911 2.0 liter of the same period.

The 64xxxxx can also be for SC engines from 80-81, but they would begin with 640xxxx or 641xxxx. Beginning in 82, the 3L engine used letters in the third position, 64C for 82, 64D for 83, etc.

Thanks mate!

you can always look your engine up here.

Can anyone tell me if the Vin on 1969 911T matches the engine?

Vin- 119121781

Engine - 6196073

Yes, Karman built. "2" in the VIN 5th position.

To be a little more precise, the VIN indicates a 1969 Karman coupe, and the engine number also indicates a 1969 U.S. version T engine, fit to a Karman chassis. The engine and chassis numbers are consistent, but they do not necessarily match.

"Matching numbers" generally means the engine was installed into that particular car at the factory, and the numbers for both were recorded. The only way to know if your numbers are matching is to contact Porsche. A COA will have the matching numbers, or you may, possibly, get Porsche to simply confirm if the numbers match without having to purchase a COA.

IMO, given you have a Karman chassis and a designated Karman engine, the odds are they are factory matching. For absolute certainty, however, you will need confirmation from Porsche.

This is good to hear. I just bought this car and the seller expressed that it was a numbers matching car. Thanks for your help.

Hello Guys,

I'm brand new to this Porsche thing and I've read through all 22 pages but I'm still a little confused as to what kind of motor I have. I'm hoping I can get some help!

Engine Code: 6271792
930/06

I can see I have 6 = 6 Cylinders, 2 = "S" Model for US? 7- 1977 Year

I've read it could be a 911/85 motor which seems to be a 2.7L or is it a 3.0L since it's a 930/06?

Hoping it's a 3.0L haha?

Thanks Again,

John

Here's the problem I'm having, at least with my source. Your engine number does decode to a 1977 S, US version. However the type number, 930/06, does not appear until the 1978 and 79 years and they are for US, California specific cars. The only 3.0 engines I see for 77 are type number 911/44, 48, 49.

Now, my source may not be completely accurate, or you misread the type number or engine number.

Thanks for the Quick reply.

I'm attaching pictures and I pretty sure I'm reading it correctly. I was told the motor was rebuilt. I just don't have any documentation.

Thoughts?

The picture of the engine type number is clear and almost looks new. The engine number, however is not clear. It does seem to show the number you posted. It could be original or could be a restamp as it's hard to make out the fonts and if the stars are clearly stamped at each end of the number. Your personal viewing could likely tell if the digits are as clear as those of the type number.

Regardless, unless the source I used is incomplete or inaccurate (which it has been in the past,) I cannot match up a 77 engine with a 930/06 type. Maybe someone else can chime in on this.

Thanks for your help Ossiblue! Hopefully someone else can give a novice a little information.

6271792 is a 911/85 motor which is a 2.7 911S for 1977
930/06 is a 1978 or 79 911 SC US-Calif.

What you have is a Frankenmotor; the serial # has been stamped over the original serial.

Thanks everybody, It's hard to get a clear picture via my phone but I have *6271792* and it's very clear in person, then the 930/06 is also stamped and very clear.

Do you think it started it's life as a 77' 2.7L and has been upgraded as a 3.0 hence the 930/06?

It's been upgraded as 2 plugs per cylinder also, and I forgot to point that out in my last post. Can you guys clarify what exactly "restamped" means?

Thanks again for everybody's help!

Hi all

Below are pics of the engine number on my 76 targa. Previous owner said it has a 3.0l engine. Do these numbers point to it being an early SC engine?

Numbers from the pics
6274874
930/07

Thanks
Jeff

Both Wayne and the Red book has the 930/07 from a 1980 SC but with a serial starting with 6300001-on

A full photo of the engine would ID it as a 3.0l

I cannot find and engine number that corresponds to yours--1977 US 2.7L--with a type number of 930/xx. That year engine in a 3.0 had type numbers 911/44, 48, 49.

There were 6041 engines made with the 627xxxx number (not counting sportos which began with 6279), of which 2747 were targas. Your engine sequence number is 4874, not putting it close to the end of production so it doesn't make sense that it could be an "early" 3.0.

Like the other posts in this thread, something is amiss with the numbers.
