What is a 454 Chevy engine?

The Chevrolet 454 is a large-displacement (7.4L or 454 cubic inch) V8 engine produced by General Motors. It's known for its significant power output and torque, making it popular in heavy-duty trucks, performance cars, and boats. Several variations existed over the years, with different power ratings depending on the specific configuration (camshaft, carburetor, heads, etc.). While powerful, they're also known for being relatively thirsty on fuel. Think of it as a big, powerful, but less efficient engine compared to smaller, modern engines.
