my g/f has a 98 camaro V-6 with the Y-87 package(posi, 3.42) I have a stock 2.73 gear now I know the breaks are bigger on her car and the posi works better than mine. I was wondering will this 3.42 hold up to the power as well as mine will and are all the control arm brackets the same? I'm running slicks with nitrous. thanks foer the info.

 

If her camaro is a V6 then it should have drum brakes, not disc like your car. As far as I know though the axles are the same, i never mess with v6's though. One thing to consider is if either car has traction control which will be a 4channel abs setup vs the standard 3channel. The stock 3.42s should handle the power as well as the 2.73, BUT you are still definitly pushing the envelope with slicks on a 10 bolt. You could buy a girdle for a lot less than a 12 bolt, but that will only help so much. Also, your girlfriends car is gonna be a dog with 2.73s.

I see your from Michigan, if your interested I am going to be selling my 3.42 rear end, its just sitting around collecting dust. I was keeping as a spare, but I could use the money.

 

let me know how much you want when you figure it out

and to 94formulabz yes it does have rear discs that are 2inches bigger then a 93-97 there were certain V-6's that came with dual tips, 3.42 posi, and rear discs. its the Y-87 thanx for the info though.

 

how would i know if a 98 v6 bird is a y87 package or something similar? my buddy just bought one. is there a code in the vin for it?

 

open the glovebox and inside of it will be a data plate and one of the codes on it should read y87, if its a y87

 

cool thanks. and if its not then what rear would it most likely have? nonposi right?

 

my g/f's kicks the *** end out easier than my Z its got a damn good posi unit in her
