The amount of horsepower generated by a 355 small-block Chevy (SBC) engine can greatly vary depending on several factors. A 355 SBC refers to a popular engine configuration utilizing a bore of 4.030 inches and a stroke of 3.480 inches, resulting in a displacement of approximately 355 cubic inches. However, the actual horsepower output is heavily influenced by the specific components and modifications incorporated into the engine build. Variables such as compression ratio, camshaft profile, cylinder head design, induction system, exhaust setup, and tuning play crucial roles in determining the power capabilities of a 355 SBC. The horsepower range for this engine can span a wide spectrum, ranging from milder street builds with around 300-400 horsepower to more aggressive race-oriented setups that can produce over 600 horsepower or beyond.
What Makes a SBC 350 a 355?
A 355 c.i.d is a small block Chevy (SBC) 350 that’s undergone a specific modification known as a rebuild and bore. The 350 SBC is a popular and widely-used engine known for it’s versatility and performance capabilities. When a 350 is converted into a 355, the engine block is bored out slightly to increase the cylinder bore size.
By increasing the bore size, the displacement of the engine is increased from 350 cubic inches to 355 cubic inches. This small increase in displacement can lead to a noticeable increase in power output. The additional displacement allows for larger and more efficient combustion chambers, resulting in improved airflow and fuel combustion.
The 355 conversion is often sought after by performance enthusiasts and racers looking to maximize the potential of their SBC 350. The increased bore size creates room for larger valves, which can enhance the engines breathing capabilities and increase power output. Additionally, the 355 modification can provide a higher compression ratio, ensuring more efficient combustion and a greater amount of power.
It’s important to note that the modification from a 350 to a 355 isn’t always necessary or appropriate for every application. The increased displacement may not be beneficial for certain applications, such as those that require a more balanced power-to-weight ratio or where fuel efficiency is a priority.
Now let’s dive into the specifications and details of the 355 Chevy motor.

With it’s combination of horsepower, torque, and fuel efficiency, it strikes the perfect balance between performance and practicality.
Now, let’s dive into the details of what makes a 355 motor Chevy so unique and sought after in the automotive world.
What Is a 355 Motor Chevy?
A 355 motor Chevy refers to a specific type of engine commonly found in Chevrolet vehicles. It’s essentially a modified version of the popular 350 engine. The term “355” represents the engines displacement, which is calculated by the combined total volume of all cylinders in the engine. In this case, the engines displacement is increased to 355 cubic inches.
To achieve this larger displacement, the 355 Chevy engine utilizes an overbored block. This means that the cylinder bores are enlarged to accommodate larger pistons, resulting in a higher displacement. The process of overboring involves machining the cylinders to increase their diameter, allowing for larger pistons to be inserted, thus increasing the overall displacement. It’s important to note that this modification typically requires a rebuilt engine.
In addition to the overbored block, a 355 motor Chevy may also feature newer pistons and rings. These components are often upgraded to ensure optimal performance and durability. With newer pistons and rings, the engine can achieve improved compression ratios, enhanced combustion efficiency, and better sealing, resulting in increased power output and overall engine performance.
The larger displacement of the engine typically translates into increased power and torque, providing a more exhilarating driving experience. This modification can be particularly attractive for individuals who enjoy high-performance applications, such as racing or street performance.
As a result, the engine can deliver improved performance, making it an appealing option for those seeking a more powerful driving experience.
The horsepower output of a Chevy 350 small block engine varies depending on several factors such as the year, make, and model of the car. Generally, it can range from around 145 to over 370 horsepower. Keep in mind that modifications and upgrades can also significantly increase the engine’s horsepower.
How Much HP Does a Chevy 350 Small Block Make?
The Chevy 350 small block engine has proven to be one of the most iconic and versatile powerhouses in the automotive industry. With a displacement of 350 cubic inches (5.7 liters), this V8 engine has been a trusted choice for car enthusiasts, hot rodders, and even racers. When it comes to horsepower, the range can vary depending on various factors such as the year, make, and model of the car.
In more recent years, the power potential of the Chevy 350 has significantly increased. With the introduction of fuel injection systems and modern engine management, the horsepower figures can now reach well over 370 in certain applications.
It’s important to note that horsepower figures can also vary depending on modifications made to the engine. Many enthusiasts choose to upgrade components such as intake manifolds, camshafts, cylinder heads, and exhaust systems to further enhance the power output of their Chevy 350 engines. These modifications can increase horsepower figures even more, allowing the engine to produce an astonishing amount of power.
With advancements in technology and modifications, enthusiasts can unleash even more power from this versatile engine.
