...Early (1966) SOLEX "Splash Lube" Cams. Since I should not use 906 cams for my street engine, I selected the SOLEX cams instead. These are probably the BEST "all-around" Porsche High-Performance cams for the street. More aggresive than the "E" and NOT as "peaky" as the "S" profile. I recently acquired this pair and they are in very good condition. Good luck finding a pair. Those who know about these cams are keeping them and they are getting more difficult to find these days! ; )
