Power Valve

For dual, or triple carburetor setups be sure to match the carburetors. The Holley 94 uses a power valve, which normally runs at 7.6HG. When running 2 or 3 carburetors you will need to reduce the size, or you will get too much gas at power. Typically on a tri-power this is done by changing the 7.6 power valves out in all three carburetors for 2.5 or 3.0 valves.
