Many car enthusiasts often come across the challenge of identifying small block engines correctly. It’s not always easy to tell the difference between a 350 and a 400 small block engine, but it’s important to know which type you’re dealing with. This guide will help you learn how to tell the difference between a 350 and a 400 small block engine.
What is a Small Block Engine?
A small block engine is an engine that has a smaller displacement than a big block engine. Small block engines are generally lighter and more compact than big block engines, making them ideal for a variety of vehicles such as cars, motorcycles, and boats. Small block engines have been used in many different vehicles since the 1950s.
What is the Difference Between a 350 and a 400 Small Block?
The main difference between a 350 and a 400 small block engine is the size of the engine. The 350 small block engine has a displacement of 350 cubic inches (5.7 liters), while the 400 small block engine has a displacement of 400 cubic inches (6.6 liters).
In addition to their different displacements, the 350 and 400 small block engines also have different cylinder head configurations. The 350 small block engine has a four-barrel carburetor and a two-valve configuration, while the 400 small block engine has a four-barrel carburetor and a three-valve configuration.
How to Tell the Difference Between a 350 and a 400 Small Block
There are a few ways to tell the difference between a 350 and a 400 small block engine. The easiest way is to look for the displacement number stamped on the block. On a 350 small block engine, the displacement number will be “350”, while on a 400 small block engine, the displacement number will be “400”.
Another way to tell the difference between a 350 and a 400 small block engine is by looking at the cylinder heads. On a 350 small block engine, the cylinder heads will have a two-valve configuration, while on a 400 small block engine, the cylinder heads will have a three-valve configuration.
