406 cubic inches .
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.

Figure the volume in cubic inches and divide by 277.4 to get the number of gallons the container will hold. This is A close approximate formular. Convert the gallons to pints or less if it is a small container.
This is a pretty straightforward conversion. One cubic foot is equal to 7.48 gallons (US). If you take the reciprocal of that figure (1 / 7.48), you can determine how many cubic feet are in one gallon: 0.134. That is, one gallon is equal to 0.134 cubic feet. So, one gallon per minute equals 0.134 cubic feet per minute. But you're not done, yet. Since there are 60 seconds in a minute, you must divide that figure by 60 to determine how many cubic feet flow in just one second. 0.134/60 = 0.00223 = 2.23E-3 cubic feet per second. That's a pretty small number to work with. It might be more useful to convert that to cubic inches per second (although you didn't ask for the answer in those units). Since a cubic foot is equal to 1728 cubic inches, you can multiply the answer above by that number: 2.23E-3 x 1728 = 3.85 cubic inches per second (in3/s).

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 )
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 )
BIG BLOCK OR SMALL BLOCK DOES NOT DEPEND ON CUBIC INCHES . IT IS THE DESIGN OF THE BLOCK ITS SELF.

A 400 small block engine that is 0.060 over means the cylinders have been bored out to increase their size. The original 400 small block engine has a standard displacement of 400 cubic inches, but when bored 0.060 over, the engine's cubic inch size would increase to approximately 406 cubic inches.

The 390 Ford motor is an FE block and was made as a Big Block only. The small block or Windsor motor could be bored and stroked to have 390+ cubic inches. To build a stroker motor you have to do extensive machine work and parts matching. That process usually involves large amounts of money.
