in short
After providing my lobe number to my Comp Cams rep... his response:
"YOU CAN'T REV THAT LOBE" !
me:
"THAT'S WHAT I'VE BEEN TRYING TO TELL YOU" !

Yes, there ARE lobes that can't be controlled at RPM... "torque lobes", as they were described to me.

I remember trying to work with you on that.


And that was my first thought on this thread.
