Hey guys, I'm sorry if this question has been asked before. I searched and could not really find much information. I basically want to know how fast you guys/girls are going on stock 8.5 rears. I currently have a 7.5 in My Oldsmobile Cutlass running mid 13s on street tires right now. I'm hoping to upgrade to an 8.5 or something, get some slicks, and break into the 12s. The 8.5 Looks like it will be the easiest and cheapest way to go but I don't want to worry about having parts break on that also. Do you guys recommend putting in C-clip eliminators and alxes for a 12 second car? Thanks for any help
