ive been looking at sets of axles and i am wondering if 4.56 is too much for 35 inch tires. sometime later i plan on 37's. i have an 85 k5 with the 350 with mild cam and headers/700/208 and right now its got the 3.08 in it. what will i experience with 4.56 or 4.11 (if thats better?)with mostly highway driven vehicle and the occasional muddy weekends? i drive about 60 miles a few times a week for school and really dont want to mess up my newly rebuilt trans (6K) mileage is a factor but i dont really mind buying gas. are highway rpms going to be too high with 4.56 as opposed to my 3.08? and which one will have a better final drive ratio? anybody running 4.56 with a 700 and like it or dislike it? sorry for the really long post and all the questions but i think i found an alright deal on a set and alot has been on my mind about it lately. thanks again! really!
