RE: 07 4.3L v6 nbs - 4/6/2008 4:43:39 PM    northey87 Posts: 847 Joined: 10/17/2007 Status: offline If you switch for those to 2.91, you will probably get worse mileage. 3.21 are are already highway gears and if you go in the direction of 2.91 then your engine will (yes, have less rpms at higher speeds, but) have to work harder to get up hills. Thats probably why your mileage is only 13.5, because engine is already working really hard to get up hills or starting from a stop. I would head in the direction of 3.43 or 3.73 gears. I have 3.43's and am getting 15-18. _____________________________ ''''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.
