Brand new Holley 2 Barrel 330cfm carburettor designed and manufactured in Australia to suit the Holden Red Motor 6 Cylinder engines. Carb is sized at 330cfm with annular boosters fitted for improved atomisation at low air speed and bottom end torque. Metering block re-calibrated: main, power and pump circuits to suit the 6cyl engine to maximize fuel economy. This carb is designed and engineered for 6cylinder use. We have had various Red Motors dyno tuned to a close figure that will suit a standard Red Motor, regardless of capacity. This helps us provide the right calibration settings for optimum efficiency provided the ignition system is working correctly (points set correctly, timing set as instructed, vac advance working correctly). We supply electronic conversions and Vacuum Advance cans if needed. For more modified engines, the kit will still work fine however fine tuning can be done to better optimize your engines performance.


The air filter is a chrome 9" x 2" high. You also have the option of replacing the 9”sports filter element that we provide with a 9” K&N filter element. K&N Filters have a reputation in their Air Filtration systems that produce a higher air flow as well as better filtering of dust and dirt that a normal standard element would do. This element is a washable and reusable element which is perfect for serious off road use. We also sell recharge kits to bring the element back to the shape that you bought it in. (See “Air Filter Options” drop down box).

The bowl assembly features an aluminium construction and presents well. The metal is easily polished and has significant defense against corrosion, unlike the new shiny metal Holley Avenger series which is simply the bare metal without a coating. The bowl also features the classic Holley fuel bowl "window", now facing away from the engine! This makes it far easier to check the fuel bowl internals without having to lean directly over a hot engine.
Furthermore the fuel inlet has been moved away from the tappet cover, and the heat surrounding it.

Our workshop line is open business hour for assistance fitting should you need it.
The carburettor is supplied with no choke, however a manual choke is available.

The kit also includes a brand new Redline manifold, Australian made.

We also sell a 350 Holley that is more orientated for Traditional Motorsport use. See related products.
