What Rear End To Go With ...???

[chadis]

well First off . I own a 1987 camaro iroc.. last april i bought a new crate engine from gm say.the data sheet states (320hp..360lb tourqe). well my rear end didnt like that what wonce was limited slip is now all slip one wheel peel..... my question is what should i replace it with ,, now i like the gear ratio that i have (3/27) i just want something that will hook up and lock in nice. i have been told to use a eaton limited slip locker .? there is so many choices to choose from??? some guidance would be nice??

I'm partial to 3.73's myself.

i think he was referring to carrier, rather than gear ratio.

depends on how much you want to spend on it. cheapest way is to get a posi/lsd carrier from a 4th gen, and make sure you get the right series for your gearset, which is a 3 series iirc.

if you want to spend some money on it, get either a 12-bolt or a ford 9"

I would get a new ring and pinion set while you're tearing into it. Just a thought.

Is IT really worth changing out my whole rear end ,,??? can't i just buy a new gear set and posi ?? wouldn't that be the easiest i agree not the cheapest but i got some money saved for it

switching out the carrier and gearset IS cheaper than the whole rearend. from what i've read, the weakness is in the ring gear, so if you get a 2 series carrier and say a richmond 3.73 gear set for a 2 series carrier, you will get a ring gear that is twice as thick, and imo, that will be a lot stronger.

i just thought of something, you said you have 3.27 gears. are you sure of this? If so, then you have the somewhat rare 9 bolt rear end.

The 9 bolt is known to be stronger than the 10 bolt that most 3rd gens have. It will be very difficult, if not expensive to find a new carrier that will fit. You just may have to replace the entire rear axle assembly.
