What are the stock m42 cam specs?

Not sure on the Duration, but stock lift 9.5 I believe.

I think the duration is 245, and lift is about 9.5, like Chad said.

Official specs:

240 degrees duration

http://www.integralcams.com/bmw.htm has yet another number for stock specs.

Hmmm. Interesting. Got my numbers out of January 2005 Roundel article on the M10, M42, M44 and S14 motors which is supposedly a reproduction of BMW NA specs.

Actually, the numbers at the URL aren't too far off of what I quoted. 242 degrees vs. 240 degrees duration and 9.68mm versus 9.7mm lift. This *could* be within tolerances.

The Bentley manual doesn't have the camshaft specifications. Darn.

Just to make things slightly less clear, I believe there is some adjustment to them as well, however, I haven't heard of anyone taking advantage of that to make lots more power.
