Have not tried it but I would expect more top end, no notice of loss on low end and no jet changes. I assume you have already rejetted for performance.

I have run about every combination of E and S cam, carb and compression on an E motor and can confirm what most people will report. Carb makes the big difference, cams and compression are less noticeable. The E cams pull longer on top and that is what you will notice. With E cams you will curse the S rev limiter setting.

Should be a need to go slightly leaner as well I would think.
