Adjustable Metering Plate Kit Suit Holley 750 Vac List 3310

• Upgrade to Jet Tuning – Converts Holley 4160 & 4150 carburettors with fixed metering plates to accept standard replaceable Holley main jets.
• Wide Compatibility – Works with Holley, 750 Vac 3310  carburettors featuring Centre-hung fuel bowls.
• Complete Kit – Includes adjustable metering plate, notched float for clearance, gasket, and Phillips-head screws.

This Adjustable Metering Plate Kit is a direct replacement for Holley 750 vac and is designed to convert 4160 /4150-series carburettors with fixed secondary metering plates into tuneable units that accept standard Holley main jets. Ideal for performance tuning or modern rebuilds, it allows precise fuel mixture adjustments without replacing the entire baseplate or fuel bowl setup.

The kit includes a notched float for clearance of the jets, a new metering plate gasket, and Phillips-head screws to replace older-style clutch head fasteners.

Important Notes:

• Main jets are not included and must be purchased separately.
• Requires externally adjustable needle and seats.
• If your carburettor has a power valve cavity on the secondary side (common in early 3310 models), you will need to use the  “Cavity”  plate to replace the original steel block-off plate that covers the cavity.

Compatible with Holley 4160/4150-series and other aftermarket models using centre-hung fuel bowls.
