350 Idle Speed?

350/350, RV cam, headers, 4 barrel Quadrajet carb. Anyone have any idea what the approx idle speed would be? Carb was rebuilt and idle is high.

Re: 350 Idle Speed?

So what your saying is have someone hold their foot on the brake in gear while i hook up a tach and adjust it?

700-750 in park. Put it in gear and you should have 550-600.
