I fired up the engine yesterday, let it warm up, and adjusted the new Proform 850 Racing Series carburetor idle mixtures and idle speed. I had an intake manifold vacuum gauge connected and it showed 11 inches of mercury @ 1,000 RPM idle. This sounds reasonable since I am running a Crower 00427 mechanical roller cam, 290 degrees intake (advertised) and 260 degrees @ 0.050 lift.
It sounds good and the throttle response is very crisp. Far better than the old Holley.
