Ok, as most of you know, my camaro is in florida and I am in ohio, so if it werent for that I would find out for myself. According to this: http://www.iroczone.com/specs/camaro/camaro86.html

I could only have a 3.23 rear end. The car is an 86 Z28 with the LG4/5spd. According to the chart, the HO LG4 was only used in the Z's, and then the only rear end available with that combo is the 3.23. Another question, is the 3.23 an LSD rear end?

 

IIRC it is, I know the RS was a one wheel squeel, but the z28 and IROC were ltd slip...

 

My RS.. belive it or not. came factory with 3.08 LS. Has the G80 tag on it... go figure right?

 

my 84 had 3.23 with a open carrier until i put a posi 4.11
