Did you pull those spec's from the "old" pipe shootout runs?  On monday I can review the specs on that old gas drag motor. Been a couple years since it ran that way, but I'm thinking those are good numbers.  I switched to alky on that motor.  My small reed with the 44 is running at 560/580.  I like em a little on the edge far as the main goes...I do make sure the needle position and needle jet are safe for duning thru the bowls.
