All right guys, its my understanding that the only differences between the 1987-1990 Camaro’s is they came in three option classes, IROC, Z-28, and RS. Furthermore, in 1991-1992 there were some minor interior/exterior changes.

The IROC’s weren’t anything to special, tuned port injection, different spring rates, bigger tires, bigger rims, bigger sway bars, the like, nothing that couldn’t/wouldn’t get replaced on any car I get, Z-28 were a step down, some came with carbs, but the basic options were still there (ie: 5 speed, and all other interior options that came on the IROC’s), And the RS was an anemic Camaro that had a 6 banger, here is where my question arises, what are the exact differences in the RS and the Z-28, I want to buy a Camaro and swap a used 1994 LT-1 with a T-56 six speed, so the engine part is not really that important. Did the RS’s come with different gauges? Did they come with a different rear-end Gears? I need to know specifics. I would really appreciate a lot of pictures with this one guys.

Now about the swap, would it really be feasible to do a 5.7L T-56 swap into a third gen that came w/ a little 6 banger?

 

You are incorrect sir...the iroc was an available option on 85-87 z28's while the iroc replaced the z-28 from 1988 till 1990 and the other options those years we're as follows:


1987:
z28
Iroc
Sports couple (optional LT package)
RS (v6)
convertabel was introduced

1988:
z28 dropped and replaced by Iroc
RS(v6)
Sports couple

1989:
sports coupe dropped
RS (v6 or v8)
iroc Z
1le package became available

1990:
last year or iroc
RS(v6 or v8)
new interior designs for all camaro's
only half a production year due to lose of iroc contract

1991:
iroc dropped and Z28 returns
RS (v6 or v8)

1992: same as 91

 

I know that the z went to sleep for a while but i assumed that we didnt need to go there. but thnx for the info.
