Thank you so much!! With the 4:11 is it a posi/limited slip rearend? Would a 400 transmission work or 350? I would like to keep the rpms down on the freeway here in the twin cities. Will i be able to keep up with traffic @ 65-70 mph? New to this truck. It has a 1974 350 police interceptor engine in it currently. Thanks for your help.
