Gonna have to jump on the disagree train here as well. I'm running the cam I got from @PRH that was originally spec'd for my 360 build. [email protected], 370 lobe lift, mech roller. In the 416 I ended up building it's idle is like a kitten purring and it pulls 16 in/hg. I wish I'd done at least another 20deg and .020, but cam cores were getting thin even back in early 2020.
