A Chevy 383 Stroker engine is a hybrid engine made using a 350 small block and adding a Chevy 400 crankshaft. This combination adds more air and stroke to your engine’s performance, and you get an increased stroke length from the stock 3.48” to 3.75”. This increased the displacement to 383 cubic inches, and this is why it’s known as a 383 and not a 350.

How To Find A good 383 Stroker Carb?
Consider also that most carburetors for 383 Stroker engines will be refurbished, remanufactured components.
The Quadrajet is a four-barrel carburetor, made by the Rochester Products Division of General Motors. This model was first used in 1965 on the Chevy 396ci engine, and its last use was the 1990 Oldsmobile 307 V8 engine.
You will notice in this review that most of the carbs are Rochester style, this means that these are either remanufactured, refurbished or brand new copies of the original Rochester design. All pre-1976 Rochester carbs including the Quadrajet were designated M4, M4C or M4V, and came with a seven digit numbers and these started with 702 and 704 followed by a number such as 2, which stands for Quadrajet, and a 5 which were designated for California emission standards. After these digits followed the make, such as 4 for Buick, or 5 for Oldsmobile and so on. I won’t go into all the numbers, but you get the picture.
Post 1975 the designation changed to M4ME replacing the M4V and M4MC replacing the M4C. These were used for specific applications, for instance, the M4ME was used on 1985 to ’88 Dodge trucks with a 360 engine.
Later models were designated E4ME and E4MC; these are designed to communicate with the ECU’s of the modern computerized vehicle. I know that this explanation is a bit sparse, the reason being that this is a long subject with a lot of data to comprehend and I just wanted to give you a basic understanding of how complicated the carburetor aftermarket really is.
Quadrajet vs. Twin Carb.
Basic carburetors have only one venture (barrel), many carburetors two barrel configurations and then there are the four-barrel configuration, or Quadrajet style, which are used for higher air flow and performance style applications.
The main difference between a two barrel and four barrel is the amount of airflow into the engine, as such the Quadrajet comes with two primary venturis (barrels) and two secondary barrels, both of which are smaller in size than the barrels of a twin carb, but when combined, these four barrels are capable of delivering 750 cu ft (21,000 l)/min (cfm) maximum.
A Chevy 383 outperforms a standard 350 on all counts. That is why a Quadrajet is the best carburetor for performance to add. The Rochester Quadrajet design will give your engine that much needed 750 cfm, and this, in turn, will boost your performance magnificently.
If you are already investing in a golden oldie, and you have a 1970’s 383 Stroker, I strongly urge you to consider a Quadrajet over a 2 barrel. I have presented you with the top rated of both categories, but taking a 750 cfm over a 650 cfm for the same price is, in my opinion, good maths.
