However, some popular and generally well-regarded options for different applications include:
* For a mildly modified street engine: A readily available, rebuildable, and relatively inexpensive carburetor like a Holley 600 CFM or Edelbrock 600 CFM is often a good starting point. These offer a good balance of performance and drivability.
* For a more heavily modified street engine or a mild race engine: A larger carburetor, such as a Holley 750 CFM or Edelbrock Performer RPM might be necessary. These provide more airflow for higher horsepower applications.
* For a high-performance race engine: Options like larger Holley double-pumper carburetors (e.g., 850 CFM or larger), or even professionally-tuned, purpose-built race carburetors, are common. These are generally more complex and expensive.
Factors to consider when choosing a carburetor:
* Engine modifications: Camshaft, heads, intake manifold, compression ratio, etc., all influence the required CFM (cubic feet per minute) rating of the carburetor. A carburetor that's too small will restrict airflow and limit power; one that's too large can lead to poor drivability and fuel economy.
* Intended use: A street-driven engine needs a carburetor that provides good throttle response at low speeds and decent fuel economy. A race engine prioritizes maximum power output regardless of drivability or fuel efficiency.
* Budget: Carburetors range in price from a few hundred dollars to well over a thousand.
* Experience: Some carburetors are easier to tune and maintain than others. If you're not comfortable working on carburetors, you might want to opt for a simpler design or seek professional help.
In short, you need to consider your specific engine build and goals before selecting a carburetor. Researching carburetor CFM ratings and consulting with experienced engine builders or mechanics is strongly recommended to make the best choice for your 350 Chevy.
