Yeah I get what you're saying I got mine because I was looking for a posi and I figured if I found one might as well be a upgrade from the 7.5 can't complain to much I paid $400 and it came with a new set of gears. No one likes a one wheel peel
Pontiacgp I had a 81 cutlass before I got my 87 and I ran a 255/60/15 in the rear with a 3.750 back space on a 8 wide rim with no clearance issues at all but for my 87 after I swap the 7.5 for my 8.5 imma get torque thrust 2's now could you answer this for me I wanna run a 255/60 or a 275/60/15...
I have a 87 cutlass with a gn 8.5 rear if that matters imma run a 15x8 rimin the back with either a 255/60 or 275/60 tire what would be my ideal back spacing without rolling the fender lip or rubbing and imma run a 15x7 possibly 8 in the front with a 235/60 what would be a good back spacing for...
Yeah they go for the same amount here that's why I started doubting if it was a posi or not. The guy I bought off of said "back in my day they were going for $600-$800 I don't know what they're worth now" I told him rebuilt ones or good ones go for about $1,000-$1400 from what I found so far
I didn't find it either I just got lucky and put a ad on Craigslist and some guy that needed money to move had it he also had a few 9's for like $500-$600. I really wasn't trying to brag or anything everything I read on the codes are back and forth one forum will say that the 8.5 gu6 3TJ code is...
Nah not bragging haha I just keep needing reassurance on everything I doubt myself to much and I bought it a few months back. And the guy I bought off of had it in a regal it has 4:11's in it right now and the code on the axle is gu6(I think) 3tp everything I looked up says 8.5 3:42 he gave me...
awhile back I bought a 8.5 that came with new 3:42 gears for $400. Now the axle reads 3TP I looked it up now my question is that a posi rear end? If I spin the tire both spin in the same direction so I'm sure it is just need some reassurance thanks
My engine guy talked to me about the compression I just told him just keep me away from race gas and then the next day he called and said its gonna be 11:1 and I won't be able to run any less than 93 octane and up so I said alright that'd be fine. I was gonna do aluminum heads but didn't have...

Yeah I plan on racing it like my one post said it'll be more like a weekend warrior and to the track car I'm not sure what I want it to run I didn't have a exact number to aim and you're right when you said I was building the engine around the cam I had a lot of the parts already before I took...
The main use for the car is just street or strip nothing major and my engine guy said he's gonna have me at 11:1 and to run only 93 or up which I'm not complaining the most it'll be driven at one time is to break it in and after that it'll just be a weekend warrior or car show car not gonna be...

Yeah I know I never like tires sticking out of the wheel well that's why I figured a inch or inch and a half wouldn't look so bad but yeah I might just do the 275's I mean they looked pretty good on it before but the tires where dry rotted and rims were bent I'm surprised it made it all the way...
I have a 81 cutlass supreme when I first bought the it had 275/60/15 tires on the back I wanna know what's the widest tire I can go with Idc if it sticks a inch or inch and a half past the wheel well but just no to much and need a idea with what backs pacing to go with on rims right now I have...
