Street Gear Poll
This is really a fun topic! When I bought my first Duster it had a 5:13. You didn't figure MPG, you figured GPH (gallons per hour). Switched them to 2:94. WOW! Now I did not shift from 2nd to 3rd untill 110 mph I did have it up to 130 mph on it's speedo once. It had no bottom end. Next 3:23, much easier to drive. It's cruising speed did affect mileage somewhat. Not that I was looking for it. Next was 3:91. Bad mileage, higher rpm to cruise. Think it was around around 2500 to 3000 rpm for 55 mph. I like the 3:91 the best. It gave great performance on the street and was still able to cruise but at a slower speed. I drove this to the track on a state interstate 40-50 mile to a drag strip and back to race when I did. Just for fun it had duel 600cfm AFB's on it. Ended up 4:56 and spooled for full on bracket racing With 28.5 tall slicks trap rpm was around 6800 to 6900 @ 120 mph., 11:30 et.
