Holley Secondary Metering Plates

Product images may differ from actual product appearance.

Many Holley carburetors use a secondary metering plate with drilled restrictions rather than a secondary metering block with removable jets. When recalibrating the secondary side of such a carb, the secondary metering plate must be changed.
