Unusual engine code

So here's my current mystery. I bought a 77 targa converted to slant nose yesterday, and I can't seem to figure out what engine I have. Should have been a 2.7 according to vin 9117210595
However the numbers by the fan are *3280888* and 930/06

930/06 indicates 3 liter
*3280888* I find one reference to, here: Porsche Engine Numbers
But that points to a really early motor and doesn't match the 930/06
Here are pictures

Is it 930/06 or 930/08?
In the /08-case: 3.0-liter 911 SC engine for Japan

Its definitely 06. Maybe not clear in the pics but it's a 6.

RedBook says its from a 68 911 coupe #3280001-3281606 (901/14) which is probably what you have already found. Could it be a replacement case restamped to earlier number?

I have no idea what it could be Haha. I'll tell you (although I come from 2 944s), it's got a lot of pep.

Post number 6 here is my situation: Engine number question 74 911S targa
The case may be from 68, but if that's the case then it was restamped 930/06? Making it...? Unknown without a teardown?

Ah hah! Notice under the slash in 930/06, there's a 9 ground off.
New theory is a service part restamped

Pulled the motor out for valve adjust.
It has 4 journal cams which I'm told makes it 3.0
2.7 distributor and cdi box. I'm still in the process of learning about 911 motors, and this one's thrown me for a loop!

The 930 101 103 4R casting number would be SC. Serial number makes no sense. Case would not be a Porsche restamped '68.
Tom Butler gives a nice overview of engine cases.
r case designations

It's clearly NOT an early chill cast case because the longitudinal fins are missing, among other details. The casting number is wrong, too. It has a 2.7 exhaust system (one of the worst available) I suspect the numbers have been altered, or possibly it was an unnumbered case that had numbers stamped to suit the needs of the person who installed it. I think the 930/06 is authentic, I doubt the actual serial number is. Per the specs book, all 6 cylinder engine serial numbers of that era should have as the first digit a "6". This is clearly a "3". The second digit is a "2", indicating a ROW engine, the third an "8", indicating a 1978 model year. The last 4 digits indicate the "0888th" engine in the series.

Made on a Friday after lunch. Too much beer in the stomach of the tech who stamped it.

What you might have missed is that right under the slash in 930/06 is a partially removed 9, leading me to believe THAT was the restamped number. But I could be wrong

The 930 101 103 4R is part of the engine case original casting, but all other stamped numbers are suspect.
Any chance it was a '77 3.0 Carrera case?

I seem to have a faint memory of engine serial numbers preceded by a star indicate blank case stamped as replacement engine?
