Need help to ID cams
 

Hi

I have a 2.4l turbo race engine that I need to ID the cams in. They look to be 911 turbo cams stamped with MOD B. See picture. I'm looking for overlap lift setting. Took reading left bank was 4.5mm and left 5.0mm.

Sounds like one of the cam grinders has a modified version of the "Gruppe B" cam grind that was used by the factory on some of its turbo race and rally motors. If no one chimes in with anything more specific than that, you can contact the big cam grinders to see if they recognize it: Elgin, Webcam, Dougherty, and Integral.

Its an Elgin. low lift deal (.400" range) you would probably be better with an SC profile
