Is a 600 CFM carb too big for a 305?

600 isn’t too big for a 305. There’s not a whole lot of good to be said about Edelbrock carbs though, except that they’re cheap.

How do I know if my carburetor is too big?

If a carb is a little big you’ll be OK, but if it’s truly oversized you’ll have a sluggish throttle and the car will tend to bog. Think of it this way: A 950 cfm carb has a larger area to flow though compared to a 650 cfm carb.

Is a 650 CFM carb to big for a 350?

650 CFM (any brand) will be fine for your car. Re: 600 or 650 cfm carburetor for a 350? Well the quadrajet has small primaries, and huge secondaries, so actually that would probably be best for a driver…… If you must go with an aftermarket carb, then i wouldn’t go any bigger than a 650…..

How much HP will a 750 CFM carb support?

The horsepower output of a stock 350 engine also varies depending on the specific model, but can range from 145 to 370 horsepower.

How do I know what size carburetor to get?

To arrive at the most appropriate carburetor choice, there’s a basic formula: engine displacement multiplied by maximum rpm divided by 3,456. For example: a typical 355ci small-block—a 0.030-over rebuild—with a 6,000-rpm max engine speed would work well with a 616-cfm carb ((355 x 6,000) 3,456 = 616.32).

Does a bigger carburetor mean more power?

Up to a certain point, using a bigger carburetor does add more power…. assuming the engine was originally equipped with one too small to provide all the fuel/ air the engine can use. And while it sounds counter productive, it can actually mean using LESS fuel, if you drive with fuel economy in mind.

What is the ideal carburetor size?

The correct carburetor CFM size is based on the engine size, the maximum rpm the engine will be used at, and the main purpose of the vehicle, whether street or race use. The formula to calculate CFM size is (engine) cubic inches x (max engine) RPM x volumetric efficiency.
