71402BB, I think you may have the worst next to the Acki Guy but what are you doing in this thing that makes it that bad a gas milage, I used to have a 71SS with a 402, 373 gears and averaged 17MPG, You got a hole in the tank, Fule punp leaking, maybe a Dominator 1500CFM Carb. Instead of lower your gears did you ever think of switching the 4speed for a Auto w/OD. I went from 13MPG to 18 with my OD in my 67and w/cam swap jumped up to 21mpg, If you run 2.73 w/4spd this thing is gonna be a MF to take off with.

I had a 79 chev 38.5x15.50's and 3.07's. It got 12mpg with a mildly built 350. So far my 72 with 31's and a 283 gets about 14mpg. It has lower gears.

Beer so frosty, smooth, and cold it's paradise pure liquid gold. Yes beer means many things to me that's all for now cus I gotta pee. |

95 K1500, almost stock 350 (modified with bad intake valvle on #1, that gives about zero compression), L60 trans, 3.73 gears.
Gets between 12 and 14 around town, and as high as 18+ on the highway. Mebbe better after rebuild. Ed
