A tid bit for conversation....
"On Harold Brookshire cams (Ultradyne, Lunati VooDoo, etc.] Harold always wanted them advanced at least 4°, but really preferred 6°. I've advanced his cams as much as 7° with excellent results."
Paul Carter
Paul has extensive dyno experience with Voodoo lobes on various builds.
Not apples-to-apples but another tid bit to share, on all my previous solid roller UltraDyne cams from Harold had 6 degrees advance ground it. That said, all were ground with a 108 lobe separation.
