I have heard the reason for the engine size increase from 140 to 145 cubic inches was so that Chevy could brag that the Corvair engine was bigger than the 144 cubic inch Falcon, I dont' know if that's true or not but why would only increase your bore by 1/16" for 5 cubic inches? Anyone?

1/16" would increase the compression ratio assuming the rods, pistons, and heads were unchanged.

That said, the power of marketing was cranking overtime in those days, so I'd buy the theory that it was mostly done to one-up the competition.
