I am planning on doing some upgrades in the near future and I'm looking for some suggestions. I am thinking of upgrading the differential from a stock unit. I currently am running a 3.42 with a stoke limited-slip out of a 76 Camaro. So any suggestions on something that is street/ strip differential, i.e. Auburn, Eaton, Detroit, powertrax? Also was thinking about C-clip eliminators, but all the ones I've looked at have said "drag race only". Can these not be used on the street and if they are what happens? I will be installing a new stroker in the fall/winter and should be in the 500-600 hp range.
