First just wanted to say I'm new here. Long time g-body and muscle car enthusiast.
I have a 1986 Cutlass Supreme right now. It has a Chevy 383 stroker in it, extensive cam and head work, etc. It makes about 500hp on paper. It's a 3 speed 350 Turbo Trans. Now the bad part, it's still running the old stock rear end. I don't know the exact specs of the rear end for an 86 Cutlass, but I know it's junk. I'm probably only getting like less than 300hp to the ground because of it. Plus not having posi really sucks. One tire fires all day lol. I wanna throw some fatter tires on the back but I know I'll probably shatter that rear end if I do. I'm surprised it's held up this long.
I found a complete rear out of a Grand National on craigslist for $300. It's posi with a 3.73 gear. It seems like a good deal. My question is how hard is a rear end swap on this year cutlass? Would that rear end be a good one to get? If not why and what's a good one? The Cutlass doesn't use leaf springs which is kinda a weird thing (at least for me and the cars I'm used to working on).
Any help and advice would be greatly appreciated.
