What is a Big Block Engine?
A big block engine refers to a large-displacement V8 engine, typically with a cylinder bore of 4 inches or more.

Big block engines have more metal and more or larger cylinders. They tend to produce more power and torque because of their weight. Small blocks are just that — small or smaller than big blocks. While small block engines still have metal and cylinders, they are typically smaller and fewer in number.
