Default 11 mpg ???
I have a 427 FE sideoiler, single 4, 4 speed & 350:1 gear. My tires are 15's & 26.5 dia. She's a thumper with 500+ hp. I did 200+ miles today in the white mountains N.H.. Up the Kangamangus hwy. & back home. My foot got a little heavy more than once I got 11 mpg average!! About the same as my snowmobile But way more fun Me thinks something is afoot with your sbf You might consider fuel injection! it usually improves milage alot Or a rebuild
