Here's quick easy and simple answer 350ci is the total volume of all eight individual cylinders of the engine in cubic inches added together 350ci divided by 8 = 43.75ci volume per cylinder bored .040 over which means forty thousands of an inch overbore means that you enlarged the entire bore from top to bottom by forty thousands of an inch over it's entire circumference the reason it is done is because the cylinders have worn to the point that even with new piston rings the tolerances would be out of factory specs. so you bore it out .040 then you have to buy new .040 over pistons and rings then do everything else you need to do to put the engine back together and you have a Chevy 350 bored .040
