The Chevy 489 cubic inch (Ci) engine is typically a custom-built engine, often created by stroking a 454 cubic inch big block. The common bore and stroke for a 489 engine is usually a 4.310-inch bore and a 4.00-inch stroke. This combination allows for increased displacement and enhanced performance, making it popular for high-performance applications. However, exact specifications can vary based on the specific build and components used.
