Anyone running one of these Oregon cam grinds?

I think you might have a thread about this engine somewhere?

The fact that you added, vac and idle, tells me the 230 would fit the bill. Both look geared toward a stock head with a street exhaust system style grind. All the 230's i've run produced somewhere in the 10/12'' of vacuum range and had great mid range torque although they did seem to fall off in the upper 5k range.
