dw-satx, I realize this is an old post, but where did you come up with 266 duration for the Howard's 292002-10 cam? I have the same cam, and the advertised duration is 255; the duration at .050 is 220.

I do realize that "Advertised Duration" and "RPM Range" for camshafts can be misleading. "Duration @ .050" seems to be the more accepted standard.

Is there anyone still onboard that has used/is using this cam? I have yet to install mine and would like to know what to expect performance wise. Please don't speculate, if you don't know.
