    I have a stock 14 bolt diff and with the 37's on, I am not getting a lot of low end anymore....it is a 454, so I am guessing the stock rear is a 3.50-3.73 gear...would 4.11 or 4.56 be better.... remember, I am rarely going to see 70 mph in my new home in Hawaii.... so 55 and under is what I am looking at.
