How many cc is a small block Chevy?
The small-block Chevy doesn’t have a single cc count. It spans roughly 4,343 to 6,555 cubic centimeters (about 4.3 to 6.6 liters) across its various factory displacements. Common sizes include 265, 283, 302, 307, 327, 350 and 400 cubic inches.
Understanding the small-block family
The term “small-block” refers to Chevrolet’s iconic V8 engine family that began in the mid-1950s. Over the decades, GM offered multiple displacements within this single architecture. The exact cc depends on the specific CID (cubic inch displacement). Below are cc equivalents for representative factory sizes.
Note: 1 cubic inch equals 16.387064 cubic centimeters. Conversions below are rounded to the nearest whole cc.
- 265 in³ ≈ 4,343 cc
- 283 in³ ≈ 4,638 cc
- 302 in³ ≈ 4,949 cc
- 307 in³ ≈ 5,031 cc
- 327 in³ ≈ 5,359 cc
- 350 in³ ≈ 5,735 cc
- 400 in³ ≈ 6,555 cc
These figures illustrate the range of stock sizes that defined the classic small-block era. While aftermarket stroker kits and builds can push displacement beyond these numbers, the stock small-block lineup sits within this spectrum.
Practical takeaways
Among enthusiasts, the 350 cubic inch engine is the most ubiquitous representative of the small-block era, with 327 and other sizes also playing prominent roles in different Chevrolet models. The 265 and 283 were earlier entries in the family, while the 400 represents the upper end of the classic lineup before newer engine families became prevalent.
For precise displacement in cc for a specific engine, identify the exact CID (and year/model) and apply 1 in³ = 16.387064 cc to convert.
Summary
In short, there isn’t a single cc figure for the small-block Chevy. The family covers about 4,343 to 6,555 cc (roughly 4.3 to 6.6 liters), with common factory sizes including 265, 283, 302, 307, 327, 350 and 400 cubic inches. If you need the exact cc for a particular engine, determine its CID and convert using 16.387064 cc per cubic inch.
What cubic inch is a 5.7 Chevy?
A 5.7-liter Chevy engine is 350 cubic inches, which is a standard displacement for GM's small-block V8 engines, often referred to as the "350". While the "5.7L" label is often used as a rounded figure for a 350 cubic inch engine, some variations, like the LS1, are slightly smaller at 346 cubic inches (5.665 liters).
- Standard 5.7L: The most common Chevy 5.7L engine is the 350 cubic inch V8, which is a very popular and widely used engine.
- Rounded vs. precise: 350 cubic inches is approximately 5.7 liters, so it is rounded to 5.7L for many applications.
- Variations: Some 5.7L engines, such as the Gen III LS1, are technically slightly smaller at 346 cubic inches (5.665 liters).
- Other 5.7L engines: Other Chevy 5.7L engines may have different displacements, such as the 345 cubic inch engine which is also considered a 5.7L engine, according to JEGS High Performance.
What size is a 350 engine?
A "350 engine" refers to a 350 cubic inch displacement, which is a 5.7-liter, V8 engine, most famously the Chevrolet small-block V8 that debuted in 1967. The "350" in the name describes the engine's size by indicating the total volume displaced by all of its eight cylinders as the pistons move.
- Displacement: The total volume of the engine's cylinders, which is 350 cubic inches or approximately 5.7 liters.
- Engine Type: A V8, meaning it has eight cylinders arranged in a V shape.
- Origin: Developed by Chevrolet and introduced in 1967, it became a popular choice for a wide range of vehicles, from muscle cars to trucks.
- Performance: Horsepower and torque can vary significantly depending on the specific model and year, but the engine is generally known for its power and is well-suited for towing.
- Bore and Stroke: The bore is 4.00 inches and the stroke is 3.48 inches.
Is a 350 and a 5.7 the same motor?
Yes, a 5.7L is the same as a 350, as "5.7" refers to the engine's displacement in liters and "350" refers to its displacement in cubic inches. The Chevrolet 350 is a well-known small-block V8 engine with a displacement of 350 cubic inches, which is approximately equal to 5.7 liters.
- Displacement: The "5.7" is the engine's size in liters, while "350" is the same size in cubic inches (5.75.75.7 liters is approximately 350350350 cubic inches).
- Engine family: The 350 is part of the classic Chevrolet small-block V8 engine family.
- Variations: While the displacement is the same, there can be variations in specific models due to differences in fuel delivery (carbureted vs. fuel-injected), block casting, and other components.
