A 489 cubic inch (ci) engine typically refers to a big block V8 engine often used in high-performance applications. The bore and stroke measurements can vary depending on the specific engine build, but for a common 489 ci engine, the bore is usually around 4.310 inches, and the stroke is about 4.250 inches. These dimensions contribute to the engine's displacement and overall performance characteristics. It's important to note that different manufacturers or custom builds may result in slight variations.
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.
Enlarging the cylinder bore will increase cc's in a 2 stroke and ci's ina 4 stroke.....
3.68 bore x 3.126 stroke
rule of thumb here anything under 400 ci adds 5 cubic inch per .03 over bore. at 400 and over cubic inch, every .03 overbore adds 6 cubic inch. heres a formula bore X bore X stroke X number of cylinders x .7854 = cubic inch 427 chevy 4.25 bore 3.76 stroke =426.72 CI

Bore the block .040" oversize and put in a 4" stroke crank.
The bore & stroke of each cylinder. bore X bore X 0.7854 X stroke X numbers of cylinders = example 4.001 X 4.001 X 0.7854 X 3.480 X 8 = 350 cubic inches.

Normal Bore is 4.0, Stroke is 3.98. 30 over bore is 4.030. Radius of new bore is 2.015 Volume of 1 Cylinder is ((2.015*2.015)*3.14)*3.98 or 50.74 per Cylinder 6 Cylinders so new displacement is 304.45 CI
Not that I have ever heard of in stock form.
The CI stands for compression-ignition engine also known as a diesel engine. The CI engine is classified as an internal combustion engine.
No, you silly goose, the 2.3 liter 140 CI ford engine has a bore diameter of 3.78" and the Chevy 350 has a bore diameter of 4.0 inches... :)
