@yellow rose with 340 on the seat, what were you at rolling over the nose? 700? Why such big spring pressure? Was big rpm the goal? Any part numbers on the Torrington bearings or maybe a link?[/QUOTE
IIRC when I was at .750 lift it was 800 or a bit more over the nose depending on which spring I was using.
That’s what it takes to make power and shift at 8500-8800.
