Checked in with the dyno guy.
"Not sure the plugs brand, but .030 gap.
Air fuel was 12.4 - 12.6 thru the entire pull.
Timing was 33ish. Timing did not effect it, nor did air fuel ratio changes with jetting. "
The cam is making power at 5,800 so no issues there. If it would behave itself on the downside just to 6400 or 6500 I would feel safe boosting it.
It is the sudden change to a very unhappy engine that is problematic.
Seat pressure with the current springs is 160/390. With lighter springs the condition is happening at much lower RPM.
Maybe my expectations with this cam are out to lunch but we all have a gut feeling that something else is going on.
