Holley Carburettor Model Compatibility

Our Holley small parts cover all popular carburettor models including 2300 2-barrel, 4150/4160 4-barrel (600-850 CFM), 4175 spread-bore, 4500 Dominator (1050-1150 CFM), 4777 Ultra HP, and 4779 Ultra XP. Whether you're rebuilding a street carburettor or race carb, we have the correct parts for your specific model.

Why Genuine Holley Parts Matter

Aftermarket carburettor parts often use incorrect materials, poor tolerances, and non-ethanol-resistant gaskets that fail prematurely. Genuine Holley components are manufactured to exact specifications with ethanol-compatible materials, precision drilling on jets, and proper spring rates. Using correct Holley parts ensures reliable starting, smooth idle, crisp throttle response, and consistent performance in both street and race applications.

Holley Rebuild & Tuning Tips

Gasket Installation: Always use new gaskets during rebuilds—never reuse old gaskets. Apply a light film of oil to rubber gaskets before installation to prevent tearing.

Needle & Seat: Set float level to manufacturer specifications (typically 7/16" for 4150/4160 models). Check for debris on needle tip before installation.

Power Valve Selection: Choose power valve rating at half of idle vacuum (e.g., 10 in.Hg idle vacuum = 5.5 power valve). Always install new power valve gaskets.

Jet Tuning: Start rich and work down. Change jets in 2-4 size increments initially, then fine-tune in single steps. Monitor spark plugs and air/fuel ratio.

Ethanol Compatibility: Use only ethanol-resistant gaskets and diaphragms if running E10 or E85 fuel. Replace all rubber components during ethanol conversion.
