3.08 to 3.73? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Need help. Thinking of having my gears changed from 3.08s to 3.73s. Trying to decide if its worth it and if 3.73 is right. Currently running a Crate 350 with a 350TH, a 4bl carb, and 33x12.5 ATs. Its pretty sluggish know and my gas mileage sucks (about 10mpg). Will 3.73 gearing be real noticeable change and how would it effect my mileage? May eventually go to 35 but not for awhile. The 33s are only a year old. Any advise?
