so i will doing a h/c/i swap around the first week in june(have most of the parts already) and i should be seeing close to 450rwhp. my question is what all do i need to upgrade my rear end to handle the abuse from a t56 and textralia oz700. I probably wont be running slicks, but will make a few passes at the track to see how it does.
i am thinking output shafts and a dte trans/diff brace should be all i need, but could use some input on what all i will need to go with them(gaskets/bearings and whatnot) I will be doing the the mods witha gm mechanic in his garage with a lift and all his tools, just want to make sure i am not lacking any parts before we start.
anyways any advice/ part numbers would greatly appreciated
