SLANT 6 a GAS GUZZLER?

Drove a 69 Charger with a fairly new rebuilt 440/727/8 & 3/4 with 2.94 gears from VA to the Nationals in Columbus, drag raced, back and forth to the motel and drive home - all told 19MPG. Friend drove my 318/727 71 Challenger and other than no racing, averaged 18MPG for the trip. Yes, V8's can get reasonably decent mileage - and yes,wish I still had the Charger and Chally (but I'll settle for my A Bodies).
