Still think electric cars is the way to go?
I had my '70 Duster best 44.7 MPG on a strict mileage run, but still get near 40 daily driving. It had a mildly built 225, 2-bbl conversion, OD 4-speed, and something called the Power Plate under the carb. That plate not only boosted fuel economy, but it added a serious boost in power.
