A ford 302/5.0 will be 306ci if bored .030 (4.030" bore)
A small block Chevrolet (SBC) 400 engine has a stock bore of 4.125 inches and a stroke of 3.750 inches. If you bore the engine "40 over," it increases the bore by 0.040 inches, resulting in a new bore of 4.165 inches. To calculate the cubic inches, use the formula: ( \text{Cubic Inches} = \text{Bore}^2 \times \text{Stroke} \times \pi / 4 \times \text{Number of Cylinders} ). This results in approximately 406 cubic inches.
A SBC 305 bored 40 over refers to a small block Chevy 305 cubic inch engine that has been bored out by 0.040 inches, increasing its displacement. This modification typically brings the engine's total displacement to approximately 316 cubic inches. Such modifications can enhance performance by allowing for greater air and fuel flow, resulting in improved horsepower and torque. This engine configuration is commonly referred to as a "306" or "SBC 306."

A 348 Chevy engine has a stock displacement of 348 cubic inches. When the engine is bored .060 inches over, the displacement increases due to the larger cylinder volume. This increase is approximately 5.1 cubic inches, bringing the total displacement to about 353.1 cubic inches. Therefore, a 348 Chevy bored .060 over is approximately 353.1 cubic inches.

There are approximately 460 cubic inches in a 289 that is bored 0.40 over. This can also depend greatly on what kind of weight the car is holding onto.
Boring a 396 engine 0.030 inches over increases its displacement by approximately 17.7 cubic inches.
