Enthusiasts often seek a balance between cost and quality, opting for an entry-level buildup that surpasses what the factory offered during the 1970s and ’80s smog-strangled era. Aiming for a Dyno target of 325 hp, a well-assembled classic 350 can be both budget-friendly and powerful. A theoretical small-block setup would typically include an aluminum dual-plane intake, coupled with breathed-on heads and a mild roller camshaft, ensuring nothing short of a straightforward, affordable combination for vehicles like a second-gen Camaro, C10, or G-body.

Frequently Asked Questions (FAQs)

What size carburetor do I need for a Chevy 350?

When it comes to the Chevy 350, selecting the right carburetor size is crucial for optimal engine performance. A 600 CFM carburetor is often a good choice and is suitable for the stock setup, known to deliver a good performance without any additional modifications. This size maintains a balance between sufficient fuel delivery and maintaining efficiency, making it an ideal match for the everyday driver or those who appreciate the classic feel of their vehicle without the need for excessive power.

However, if you decide to add power additions such as a dual-plane manifold, a hotter cam, or aluminum heads, you’re essentially inviting more air and fuel into the engine, necessitating a larger carburetor. In this case, you would need to switch to a carburetor that can handle 700 to 750 CFM, accommodating the increased airflow and ensuring that your engine’s performance keeps pace with the upgrades. This upgrade will not only support the added power but also ensure that your engine runs smoothly under the new demands.

What is the most reliable carburetor?

The Holley stands out as the most reliable carburetor, lauded for its simple design and robust construction, especially in racing applications. It’s widely used and popular for its reliability and performance. Edelbrock follows closely, favored for consistent performance, durability, and ease of tuning by hot-rodders and muscle car enthusiasts. The Rochester Quadrajet is also revered among owners of classic cars and trucks for its blend of performance, fuel economy, and easy maintenance.

How to remove a carburetor from a Chevy 350?

When it’s time to remove a carburetor from a Chevy 350, start by ensuring the engine is turned off. Open the hood and give the car time to cool off. Touch the top of the radiator cap carefully to check the temperature and avoid burns. Remove the wingnut from the top of the air cleaner and pull the air cleaner to the side. Next, with your hands, pull off the tiny vacuum lines from the carb, and unplug the wiring harness connected to it. Use a line wrench to remove the fuel line, which should then be plugged with a rag to prevent spills. The throttle linkage should now be disconnected and pulled to the side. Finally, unbolt the carb from the intake manifold, lift the base, and pull it to the side, away from the engine.

How do you install a carburetor on a Chevy 350?

Installing a carburetor on a Chevy 350 can be straightforward with the right guidance. For a Rochester, begin by placing the vehicle in park and removing the wires from the posts. Loosen and remove the 4 bolts with a socket, ratchet, and extension, then lay a new gasket on the intake manifold. If you’re handling a Holley, start by removing the air cleaner from the stock top, then disconnect the vacuum lines and throttle linkage. After detaching the carburetor from the fuel line, remove the 4 nuts that connect it to the engine top.

For an Edelbrock, first remove the rag from the manifold and set in the new studs. Position the carb on the gasket, then secure with washers and nuts. Attach the transmission linkages to the throttle, along with the throttle return springs. For manual choke models, join the choke lever to the mounting bracket. With an electric choke, simply connect the 12 volt + to the red choke wire. Finally, ensure the vacuum hoses are in the appropriate places and reconnect the fuel line.

What is the best carburetor for a 400 small-block?

For the 400 small-block, a top pick is the Holley 670 cfm Street Avenger carburetor, perfect for engines producing 300-400 horsepower and designed for serious street performance and track duty. This carb boasts vacuum secondaries for low-end torque, crucial for street agility and weekend track action.
