Ideas for best gas mileage?
OK I know its a big heavy truck with a thirsty 350, but I need some ideas on increasing the fuel mileage. I currently average 5 to 8 MPG. Heres what I got:
'70 Chevy 3/4 ton 4x4 newer 350 V8 SM465 4 speed I believe 4.11 gears. I have a Carter AFB 4 barrell carb, complete MSD ignition system, dual flowmaster exhaust and an open element air cleaner. I am considering: 1. smaller carb (either 2bbl or 500-600cfm 4bbl)? 2. RV camshaft? 3. different exhaust setup? 4. changing out the axle gears (right now I can start out in 3rd without any problem). 5. Taller tires? Currently running LT265/75/16 Any ideas would be great! Thanks!! ![]() Colby. |
