Some info:

- The 2.0 and 2.2 'E' engines used the same camshaft.

- The 2.4 'E' has a slightly different profile, which results in the intakes and exhaust opening at slightly different times.

- The 1969 'E' camshaft profile is *not* the same as the 911L camshaft, at least according to the Porsche spec books. Henry, you quoted the specs for the 901/06 engine, which is not a 911E engine. The 911L and 911E specs are not listed in the same spec book. The camshafts are similar, which is why I believe that Elgin has combined the profiles on their website.

As for Solex cams and 'E' cams - the fact that the intake valve overlap is differnet for those two, yet the open/close and lifts are the same, leads me to believe that there is a different parabolic lobe profile for the Solex cams.

I think everyone here is splitting hairs. In my book, I wrote: "Solex Cams have a profile that is nearly identical to th early L camshafts and are in-between the performance of E and S cams.

P.S. I might add that the factory information on this subject is a bit murky. The difference in 'E' cams is documented in the spec books, but the cams have the same part number. I also went through the spec books, and corrected a lot of mis-information on a variety of topics that was printed there. The only sure-fire way of telling what these profiles were is to take original, never-torn down engines, and place the cams on a cam doctor to measure their profiles.
