I am looking to rebuild my rearend. I believe as it is now it is an 8-3/4 4.56 gear with a spool in a 742 case connected to a 3-speed trans. I would like to make it more driveable, I am wondering what set-up someone would recommend to make it more streetable. I am afraid to go all the way down to a 3.55 especially if i wont be able to do at least 70 under 3000 rpm's, really afraid to lose any performance. Does anyone have a 3peed setup and can tell me their gear size and the top speed around 3k.i also want to get rid of the spool does everyone say go with a suregrip (probably not a good question to ask) or does anyone run a detroit locker, or Auburn Gear locker, if so what do you think.also am rebuilding the trans (727 torque flight 3 speed ) i won't be doing this myself as it is beyond my skill level does anyone have any tips i should know just so i have something to go off of when talking with the transmission guy. or does anyone live in the detroit area that has recommendations i can check into. Thanks for reading this extremly long post
