[79Betty]

With my 79 350. 4" lift n 35's i was getting 13 highway. I have now straight piped it put on 3" body lift n turning 38's... 12 mpg. But if i get into it (which i do very very often) i get 8... So i can get good milage. But i do plugs rotor cap and wires every year. I've since gotten a ranger so i'm not worried about milage too much anymore, but i still like that i get above 10 lol
