I would love to get that much out of my '78 W250 360 4bbl 727 Prospector. I'm lucky to get 9MPG! :mad:When I pulled an enclosed car trailer, I got 6MPG! :wtf: About the only mod is a Holley carb. I'm thinking of going back to a stock TQ and see if that helps any. It's a fairly fresh rebuild with all stock internals and heads for that year, and an RV cam that is supposed to be good for mileage. How much worse would a performance cam have been? Jeeezz....
