It is 538.92 cc's

The mathematical equation is bore (3.736) x bore (3.736) x stroke (3.00) x 12.8704 = swept volume of 1 cylinder

........hell, I'd just do 4.3 divided by 8 = .......

That would get you into the neighborhood .

Well assuming you mean divide 4.3 liters by 8 that would only give you the liters for one cylinder NOT the CC's of swept volume. Now assuming you mean to divide the 262 cubic inches that would only give you the cubic inches for 1 cylinder and still not the CC's of swept volume.

I'm assuming the OP is trying to figure out either his existing compression ratio or needs the info to change the compression ratio by using heads with a different combustion chamber volume or pistons to achieve a different compression ratio.

Or maybe he is looking for the right value to put into his bin file since he's in the PCM section?

Volume of any cylinder is: Height*pi*(diameter^2)/4.
