WebApr 4, 2010 · 'boring' an engine does little for compression ratio. both the swept volume and combustion chamber volume will get SLIGHTLY bigger. 'slight' being the key word with an overbore. for example, take a SBC that is 350ci stock, and bore it .060 over (a pretty big overbore, probably around the max for that motor, but i'm no chevy guy). what do you … WebIn the simplest terms, a very big case pushing a relatively small diameter bullet is acknowledged as the classic overbore design. But it’s not just large powder capacity that creates an overbore situation — it is the …
