formula for measuring the volume of the a cylinder is Pi r squared multiplied by the stroke and then for total CI multiply the # of cylinders:
Bore=4.030
Stroke =3.48
Cylinders =8
3.14*3.48*(.5(4.030))*(.5(4.030))*8
10.9272*(2.015*2.015)*8
10.9272*4.060225*8
44.36689062*8
354.93512496 Cubic inches or more commonly known as 355CI
If my math is correct : using a 4 inch bore and a 3.48 inch stroke , with the cylinders bored .060 , just over ( 360 cubic inches )
If my math is correct , almost 293 cubic inches ( using a 4 inch bore that is bored out .030 and a 2.87 inch stroke )
If my math is correct , almost 410 cubic inches ( using a 4 inch bore and a 4 inch stroke that has been bored out .040 )

a Ford 400 had a 4 inch bore and 4 inch stroke. Simplest math motor EVER!! Given 4" bore x 4" stroke x pi (3.14) x 8 cylinders = 402 cubic inches. Bore this thing out .060 and you get: 4.060 x 4 x 3.14 x 8 = 408 cubic inches.
406 cubic inches .

A "400 small block bored over 30" refers to a 400 cubic inch small block Chevrolet engine that has been bored out by 0.030 inches. This modification increases the engine's displacement slightly, which can enhance performance by allowing for more air and fuel to enter the combustion chamber. The term "bored" indicates that the diameter of the engine's cylinders has been enlarged, which can lead to improved power output and efficiency.
The density of limestone varies from something on the order of 110 pounds per cubic foot (a shade over 1 ounce per cubic inch) to over 160 pounds per cubic foot (about 1.5 ounces per cubic inch).
If my math is correct , just over 311 cubic inches ( using a 3.875 inch bore and 3.250 inch stroke bored out 30 thousand )
A ford 302/5.0 will be 306ci if bored .030 (4.030" bore)
