1. 235 int / 239 ex duration with 112 deg separation
2. 239 int / 244 ex duration with 112 deg separation
Bigger cam than I expected.
I spoke to my local carb tuner. He said he could put my 750 on his "dyno" and he could fix it. I am skeptical becaus he was a bit vague when I pushed for details. His shop is pretty close to my office so I plan to stop by this week and see if his "dyno" is a flow bench.
Not sure how a flow bench could be useful in finding or fixing a stumble.
I made contact with Quick Fuel for a suggestion and should get something soon.

It looks like my cam is actually bigger than yours. Driveability around town was pretty good with the Holley 750 and really good with the Quickfuel.
