I know the red book shows a listing for a 901/09 as a 68L motor
I think having found two 901/09 engines in two ’68 911Ls is a coincidence.

The Red Book (Parernie, Patrick C., Porsche 911 Red Book 1965-1999,
MBI, 2000, Osceola, WI, USA) pages 13-17 does not show a 901/09 engine
for a ’68. On page 17 Parernie says “Type 901/09 fitted in 911E same as A
series 911L except for the following changes:….” Something is lost
in ‘translation’. He isn’t saying that a 901/09 was installed in a ’68 911L,
just the engines are similar.


The Porsche Databook, Motorbuch Verlag 2004, Albrecht
translation 2006; pp. 84-88 seems to agree.

Here are the Porsche Factory Spec Books:

For 1968 and earlier:

4203.20 2 M IV/83 (data agrees with version 1 M III/72 and
W 392-E-4000-10-68 M)

© Dr. Ing. h.c. F. Porsche K.G.




© Dr. Ing. h.c. F. Porsche K.G.



and for 1969:

4219.21, 1st English Edition, 3 M XII/71 M (data agrees with version
4210.20 1 M VIII/78)

© Dr. Ing. h.c. F. Porsche K.G.


I’m intending to be picky as these are important historical details about
our cars and need to be recorded correctly. All of the sources I listed
above (yes, rarely even the Factory Spec Books) contain errors. It is up
to us to make it clear. A century from now someone will be
researching this. God (and Wayne) willing, there will be the correct
information.

911quest, you and I know each other well enough to know I'm not
picking on you. Give me a call. You are now on the front lines of correct info.

Best,
Grady
