Posted to the bird 911 forum that I have a 6 cyl. case with numbers pictured.

One case half has 2 numbers on it. It looks as though one of the numbers is not genuine but the other is 914.

What do you guys think?

'79 SC case, based on the engine number, right?

Looks like Japan market, I think. Just guessing that's what the (J) in the engine serial number decoder means.

Where do you see a J?

I have recently been told factory warranty replacement engines have stars to designate that being the case ... I see 2 stars.... and the 640 # is six case as you know

SC case is aluminum and that case looks like magnesium.

Here is what I see the *6400653* top engine case is a 1970 914-6 Case.

The bottom case is 6190446 this shows to be a 1969 911T Coupe case.

I also do not see where you are finding the "J" in the number?

If you look at the link in JmuRiz's post it shows all the engine numbers based on the market they were made for?

I don't think the 619**** is genuine.

I don't plan on using it as its just a case but if it was a /6 case it would make a good conversation piece.

Here is a pic of the number on my 69 911T case for comparison. Looks very similar to yours. But i do not have another number near the breather on top.

On second look I see that the font size for your 911T number is huge compared to the one on my case.

Do the case pairing numbers match?

No.

If the half numbers don't match the answer is some one made the case out of two halfs.

And if they did the case is scrap.

the stamped numbers on the top do not match ???

oh I see! I'll check those.

Those are the numbers I'm talking about, different places but T1 and 4, plus the /6 has them.
If they don't match they are the halves from two different engine cases.

the side numbers cast into the lower half of the cases is prob..3R and 2R

most likely its a -6 engine someone thought they should stamp the ex 911 engine number into it.

Case halves are same number stamped in stud boss.
Part numbers are 901.101.102.2R and 3R.

Interesting, anyone looking for the original case for their 914-6? s/n 6400653

Look at the horizontal number near the flywheel, next to the oil pressure switch you'll find 901/ 38
If so, the engine IS a 914 6
The numbers on the vertical fan support are bogus.
This is easily verified.
If you don't see a type number ( in this format; 911/38.... is a 911 RS engine) on the right engine case under the fan saddle it is not a 911 engine.
Someone wanted this to appear to be 911 engine.
They probably thought it was a replacement block because it had no numbers there.

Just to close the loop, this is incorrect. Factory replacements were usually blank/unstamped cases.

I didn't see that number before. It's a 901/36.

Sorry, I failed to consider that a Euro 914 6 engine could have landed here in the US of A
A 901 / 36 is a European 914 6 engine.
NO 6 cyl. Porsche ever had the engine number and type # at that location, only the 914 6 or maybe, maybe a 904 /6
...... 2 or three were made ! or a 906 . It was put there so that it could be seen in the mid-engine location.
( BTW, thank you for the quote and for acknowledging the contribution )

I looked up the fan strap ser # and it comes back to a 79 911 SC Japan engine.
I've seen several org. 6 cases and the # stamping looks the same from the others that I've seen. With that said the ser # looks to have been added on the org 914-6 case. Not to mention that the SC case was made out of aluminum by that year.

A 914-6 engine case vandalized by some tail dragger wanna be...

I was thinking about how a euro 914/6 case could end up in Western Canada.
Best guess would be someone in the service returning home?

some got brought in when the grey market Porsche importing was big late 70-80s..one sold down in seattle area a couple of years ago. my son and I put the engine back in it so it could be transported to CA.

I actually looked at the 914-6 in 1978 and passed , it was a mess back then,rusty.. Tyler bought it, drove it 1 mnoth before the trailing arm mount tore off,,sat on jackstands since 1978

there was also a euro 72 p14-6 for sale in seattle about 1983, passed on that one also , every corner had been hit.. Its still in seattle or Arizona,, but restored as a GT lookand is grey ..og was orange

The 914 wasn't sold in Canada till something like '71 or '72 (fall '71 would be a '72 car), so the /6 was likely imported.
