There is no substitute for data logging. Why guys try to video their way to A/F data is beyond me.

If you cruise on the mains, when you lean the cruise that means smaller main jets which means you will need to open up the PVCRs to get the WOT mix back where it needs to be. And if the power valve is too late now, it will be a bigger issue with smaller main jets. I am not suggesting that that is the wrong approach. I am just noting the additional steps that need to accompany that route.

At what RPM is the timing all in? And with that big a cam, more initial may be called for if the starter will take it.
