Better MPG in an old pickup truck?
I frequent a hot rod forum. Somebody's asking about Ford engines that get good gas mileage. He's gotta '56 Ford F100 and it sounds like even if he goes with a more modern engine (4.6 L) he's going to use a carburetor. Most of the discussion is about engines and tall gearing, and somebody mentioned BSFC but it was a mystery to him, and frankly I'm not up to speed on it either. Another thing mentioned is a vacuum gauge. I vaguely remember reading articles about "RV cams" and such. What (gasoline) Ford engine would you recommend? What gearing would you recommend? Can you provide links to some good BSFC threads? BSFC charts? What else? Keep in mind that the audiences differ.
Thanks,
Kurt
