Besides...on a heavy street bike...low end torque makes a much more ridable bike that one that makes a lot of power at high rpms. Save those type of cams for lighter bikes. Touring bikes need the torque down low so they don't fall on their face pulling away from a stop light. By the way...this setup makes great low end torque!
the 37 cams pull farther up top and still have great bottom end. you have to remember it is the total combination that makes the power curve. in a stock motor the 21 is nice, I prefer a bump in compression with the 26's to make them the best they can be.
