    idle up solenoid?

    My 1979 Z28 has a ZZ4 crate motor with a 750 Holley. The car still retains its stock A/C but I need to know what to install for a idle up solenoid. I know some of the late 60, early 70's cars had vacuum operated "dashpots", just not sure what will work for my application. The car has a about a 500 lift cam and its a 4-speed. It idles around 900 rpm now but when I kick the A/C on it pulls it down to far at idle. Running at speed not an issue. Any ideas??

    Wire it up to the compressor circuit so it steps the idle up when the compressor is running.
