Help with engine numbers
 

I know this is a common topic, but all posts I have checked haven't given me an answer.

Just got a mixed up 1987 911.
Numbers by the fan are *64 1050 78* and 930725, with casting number 930-101-104-5R

Can I get some help identifying the year/size of the engine?
Thanks.

I'm back after a 4 year hiatus from aircooled 911s. Back to doing all the mods I did on the 81... or well, I never figured I'd be back, but here I am, eating my words.

The number between the two * is the engine serial number.

Can you check it again to see if the 3rd digit is not a lette by any chancer? 64105078.

Do you have a VIN?

Could the 3rd digit be a "J"?

If its an 87 (up to July) it would be an "H", a "J" would be Aug 87 to Jul 88 as an 88.

But one would not want to lead a suggestion...

So maybe he can post a pic? All I was suggesting was what I found in the Red Book.

Thanks to all.
There had to be a letter after the "64" -- will have to wait until tomorrow to check.
The VIN is WPO AB 0 91 3 H S 1 2 1812

The body is a Patritti 993, with many other changes (evidently had a turbo put in in the past, but now this 87 engine, purportedly).. So pics won't help.

Pic of the VIN and the serial # and the engine type#....

Every VIN with '091' in the middle per the Red Book has a letter after it.....

Check both you VIN and Engine serial #, as per J.B. posting, check the 9th digit of WPOAB0913HS121812...

Probably a "G" But one would not want to lead a suggestion...
