My first car in sales was a 1968 Olds Cutlass with just the 350 automatic. Rode nice and never let me down. Gas was only 30 cents a gallon then. In that time MPG was not even a concern. It was also great before the anti pollution and smog devices made vehicles a disappointment to own. HP was close to 300; later the 350 V8 dropped to 190-220 HP.

My 1980s large V8 cars easily got 20 MPG or more. Oldsmobile 307s and Chevrolet 305s. The reason no doubt was high gearing and overdrive transmissions.
