Best Carburetor for 383 Stroker

Chevy fans may or may not know about the 383 Stroker, an engine that was created specifically for the hot-rod enthusiasts. Because it was designed with this in mind Chevrolet, the creators, never put it into production for one specific model. 

Today, hobbyists and mechanics alike love to rebuild old engines, and the 383 Stroker is a favorite for those who want to tinker with their autos and add a lot of additional power under the hood. Carburetors are an important aspect of any engine but today we are going to discuss those that are the best for this antique Chevrolet engine. 

A Quick Look At Our 6 Best Carburetor for 383 Stroker

What To Look For

Carburetors were a common part of a car engine before the 1990s came around and they found a more efficient way of getting the fuel to the engine with the right mix of air pressure. Still, not only is there an entire classic car culture that radiates throughout the world, there are still an array of 20th-century cars speeding up and down our highways. 

When it comes to the 383 STroker, you can’t just go out and buy any old carburetor. You have to find one that is the best fit for that type of engine. So, if you want to know the right carb then you need to know the engine inside out. 

The Details Behind the 383 Stroker

This engine has an altered crankshaft that increases the strokes of the pistons, which might be where it got its name “stroker.” By increasing the stroke more air and fuel are moved to the cylinders, which increases the displacement all the while not changing the engine blocks. 

As an eight-cylinder engine, the 383 Stroker uses the favored Chevrolet 350 block and the marginally modified Chevrolet 400 crank. The stock 350 has a piston stroke length of 3.48 inches and the 400 crank has a stroke of 3.75 inches. When you plug those into a formula the total displacement of this engine is 383, which explains the first part of the name. 

Chevy first introduced small block engines in 1955 with the Corvette and this type of engine stayed in the publics’ favor because they were not expensive to build, maintain or customize if needed. In 1967, the next small-block engine was introduced in the Camaro, and ever since then the Chevy 350 became a standard in the industry.

The 383 Stroker improved on that model and many of the parts are interchangeable and they are easy and cost-effective to upgrade. It has a 450 horsepower rating and a 450 lb-ft of torque, which is great for a crate engine. 

With a bore of 4  inches and a stroke of 3.8 inches, the Stroker’s displacement is 6.27L. The manufacturer recommends a Holley 4-barrel carb to fulfill the performance specs of this engine, which we kept in mind when compiling our list. 

Choosing The Right Carburetor

Life doesn’t come with a one-size-fits-all model for everyone so neither should your carburetor. We all want different things out of our engines and when we have a 383 Stroker the most important factor might be in the performance, but that could be said about any engine truly. 

Still, if you are taking the time to rebuild or revamp this engine then you want it to be ahead as soon as your foot hits the pedal. The type of carburetor you choose is imperative to your pick up time. 

What Size Are You Looking For?

Engine displacement is in direct correlation to carburetor size so you are about to select a stock carburetor without any hassles to your engine’s performance. Carburetors are crucial to the health of any engine, before the 1990s that is, and getting the correct size is essential. 

How To Size Your Carburetor

Step One 

Using the formula below, plug in the RPMs where your 383 Stroker will redline. 

(305) x (RPMS) = x / 3,456 = y CFM

Some enthusiasts have reported that a 383 Stroker will redline at 7,000 RPMs, which is quite high, but not as high as a Porsche, which can go to 9,000.

So, if your 383 Stroker does 6,800 RPMs then your results would look like this. 

(305) x (6,800) = 2,074,000 / 3,456 = 600 CFM

This is how you get the correct size for your carburetor. 

Why Sizing Is Important

CFM stands for cubic feet per minute and it refers to the airflow rating of the carburetor. 

Is Your Stroker Under-Carbureted or Over-Carbureted?

Due to the Stroker’s ability to be easily customized, you might find the block of your engine to be either under-carbureted or over-carbureted. This is what each means and how to remedy it. 

Under-Carbureted

When you install a carburetor that is too small for the engine when you reach high RPMs your engine cannot achieve its peak performance. It will restrain your horsepower and can stall operation. 

Over-Carbureted

If the carburetor is too big it could run low RMPs and cause your engine to run rich, which means that it is getting an insufficient amount of fuel, typically too much. When it runs “lean” it means too little. In the case of an over-carbureted engine, it will run “rich” and introduce too much fuel to the engine

Is Bare and Stroke Important?

Yes, it is. 383 Strokers have a  bare of 4.03 inches and a stroke of 3.75 inches. With this sizing horsepower and high revolutions are going to be prioritized. Keep this unparalleled specification in the back of your mind when selecting a carburetor. 

Displacement

Earlier we discussed that the displacement on the Stroker is 383, which is part of its unique name. This number wasn’t pulled out of the air. It is the result of an industry equation that uses the bore and stroke of the engine as factors. The correct carb will allow the correct amount of air the engine requires but not too much to engulf it. 

Other Factors

Size isn’t the only aspect of the carburetor that should dictate your choice. There are so many other factors that come into play. The engine build can have a profound influence on the way your carb performs. How you drive the vehicle that houses this 383 Stroker is another influential component. Is it a show car? Do you drive it every day?

The intake manifold type, maximum expected RPMs, exhaust system, and transmission type are only a few of the other things you need to consider when you shop for a compatible carburetor for your 383 Stroker. 

If you are so inclined you can estimate the CFM rating by using the engine’s volumetric efficiency as a clue, but, for so many of us, math is when we start to let the organ grinder monkey play in our heads. Plus, the diagnostics required to test new parts after they are installed in the car are not just sitting in everyone’s garage. 

For the 383 Stroker we suggest starting out with a 650 CFM but you don’t have to stop there. Racers who want a higher CFM can shoot for 850. If you race on the road or drag then your requirement might be different. If you drive it every day then you wouldn’t need a CFM that high. 

Looks

Let’s face it, we are all a little vain in our own way. Some people like to put on makeup and take selfies. Others like to design landscapes that are the envy of the neighborhood. We like to have amazing looking engines and you have a real beauty in the 383 Stroker. A good part of the fun in having one is to show it off when it’s looking pretty. 

There is nothing wrong with building an engine that is a bit showy. That’s why chrome is so shiny. People want to see their smiles in it. So, when it comes to the appearance of the carburetor it may be worth throwing in a little more to get the glamorous one. 

One Last Word

Before we begin listing our picks for best carburetor for a 383 Stroker we want to point out that carburetors for this type of engines are not typically ready to go the second you take them out of the box. In fact, it is such a unique engine the carb will take some tuning before it works efficiently. There may be some trial and error but be patient. You’ll get it.
