327 SBC with a 1850 600 Holley. No Vacuum on the Metering block at idle and the car idles with the Idle screws all the way in, throttle screw all the way out and adjusted Floats. Currently had a 6.5 power valve and 65 jets. Also has a pretty mild RV Cam. Also has no Vacuum issues at the Throttle body. Very rich, in my garage, so gets hard to breath in there even with the door open. Any help greatly appreciated.
