I just researched this pretty well and ofcourse you all are right, everyone I could find that went from 4.10's to 4.56 really felt the difference and not much affect on the gas, some actually gained mpg. I am not sure how the highway will be but it isn't often enough to change it. I think a solid 2500 rpms will be better then a ton of down shifting and making the engine work to maintain speed. It may be a few months because I am guessing about $2k for the total if I do it myelf maybe a tad under.
I looked up one of the sponsors Ron's (i think) any other brand reccommendation for the gears?
Thanks for the info! I have heard Auburns are good Chevy lockers and Detroit for Ford and posi up front any one?
