The carburetor comes with Holley's popular Ultra Lite Secondary system, which features lightweight and durable secondary throttle bodies. This system reduces the weight of the carburetor and improves the overall performance by reducing the inertia of the secondary throttle bodies, allowing for quicker throttle response and improved power delivery.

The Holley 4779-5 Carburetor is also compatible with Holley's electronic fuel injection systems, such as the Holley Sniper EFI and Holley Terminator X EFI. This allows for easy conversion to electronic fuel injection, providing even greater fuel efficiency, power, and ease of use.
