Look at the torque numbers on this Excel sheet produced by Engine Analyzer - from off-idle to 3,000 RPM for the 261C compared to the stock cam, and the other profiles.
Mudder, do those torque numbers seem close to what you are experiencing?
Gnarls.
If that were accurate it would explain why I prefer the stock cam over the 261. I do disagree with it going all the way to redline as over 4.5-5k the cam just falls flat on its face.
