The carburetor body is made from high-quality aluminum and is finished in a durable powder coat paint. The base gasket is made from a high-temperature material that can withstand the extreme heat generated by high-performance engines.

The L-4780 is suitable for use with both EFI and carbureted applications. It can be used with a wide range of fuel systems, including electric, mechanical, and return-style systems. The carburetor comes with a full set of installation hardware, including mounting brackets and a throttle linkage kit.

In summary, the Holley L-4780 is a high-performance 800 CFM double pumper carburetor that is ideal for street rods and hot rods. Its unique design, adjustable features, and durable construction make it a popular choice among enthusiasts looking for maximum power and reliability.
