I know (Chevy) guy that built a stroker 305 (400 crank, 3.75" stroke), I kid you not. I asked him why and he said "gas mileage." Had to buy crazy $$$ dished pistons to keep the compression pump gas with the tiny chamber 305 heads. If I'm not mistaken he used some hind of "305 Torquer" World Product heads from the '80s. A good deal on those heads probably was the catalyst for the whole build. I would have just built a 307 (3.25" stroke, basically Chevy's 318).

Seems to me a over use of theory, I never get the over focus on fuel mileage especially on a summer toy, you almost never recoup the cost, it's almost always cheaper to dump the extra $$$ into the gas tank.
