4 Barrel Carburetor Copy for Holley Street Warrior 600 CFM Manual Choke

The 1850, one of the most trusted carburetors of all time, boasts an impressive 600 CFM of airflow, vacuum secondaries, a single fuel inlet, and a mechanical choke, making it remarkably versatile. This classic Holley model features a Gold Dichromate finish for corrosion protection, providing both functional and aesthetic appeal.

Thoroughly tested and street-calibrated, the 1850C is built entirely with metal parts, ensuring durability and reliability. Its unique shiny/chromate dip finish adds to its timeless appeal. This universal carburetor is suitable for applications from 1964 and earlier, featuring a manual choke and side-hung float bowls for optimal performance.

The 1850C also boasts power valve blow-out protection, providing an extra layer of safety and reliability. The vacuum secondaries, a hallmark of the 1850, contribute to its impressive and responsive performance.

Regarding the vacuum line size, the 1/4" line is designed for the automatic advance on the distributor, while the 3/8" line is intended for the power brakes.

The 1850C is a versatile carburetor that can fit a variety of intake manifolds. Specifically, it will fit any intake manifold with a Holley square flange, known as the 4150 flange, with a bolt pattern of 5 5/8" x 5 1/8".

For a 1983 305 Pontiac Grand Prix motor, if the carburetor does not fit directly, an adapter can be used, such as one from Mr. Gasket or any other reputable retailer. The 600 Holley carburetor is sure to breathe new life into the 305 Pontiac engine.

Similarly, the 1850C will also fit a 350 Chevy engine, as long as the intake manifold has a square bore Holley bolt pattern (5 5/8" x 5 1/8"). If the 350 engine still has an intake manifold designed for the factory Quadrajet carburetor, an adapter plate like the Mr. Gasket 1932 can be used to facilitate the installation.

In summary, the 1850 carburetor, with its impressive capabilities and versatility, is a trusted choice for a wide range of applications, from classic Chevy engines to Pontiac powerplants. Its attention to detail and quality construction make it a reliable and sought-after component for enthusiasts and mechanics alike.
