is there any way that i can possibly keep it? all i hear from people is no, is it true? willing to change out almost everything to make it possible as long as i can keep tran. original. any one know how? love to hear anything anyones got to say...........thanx all. -murdoc | | |

Im not sure what year truck you have, etc., but I know mine (51 GMC 1/2 ton) came with 4.11's.
My moms 53 chev also has 411's I think. 55 is pushing it with that truck!
With that being said, you can put some higher gears in your rear end, and achieve those speeds. In the January? Classic trucks, they had an article on this same subject.
Hope this helps,

Short of changing the whole rear end there is only one option. Get a Patrick's 3.55 rear end kit. Still no 70, but 60 would be alright.
