youre all wrong 
go check the production listings on thirdgen.org
82-84 z28 was the top model
85-87 the iroc was an upgrade from the z28 model
88-90 the z28 dissapeared leaving the iroc as the top model
91-92 iroc dissapeared and z28 was the top model
as an added note from 85-87 you could not order a z28 with the 5.7 it only came in a 5.0. There was also a 5.0 iroc model during those years that had the handling upgrades many people have listed. If you have any more questions just look through the tech data on thirdgen.org because it has what models were produced with what engines during every year. hope this clears everything up

Actually the 1st year for the 350 was 1987.
The difference? The IROC-Z was the top end model as to where the RS was the base model. 1st year for the RS was 1988 and you could only buy them in 3 states, in 1989 they completely took the place of the base model camaro. Look on google for the ads for the RS, it was suppossed to be a stripped down cheaper version of the Z28 with a v8 option for a way more afordable price.
As far as an RS "not being worth anything" I have 3 digits for you. B4C.
"Then the B4C police package was added, and then it was equipped with the Corvette L98 5.7 aluminum head motor, fitted with siamesed intake runners and tubular headers. This brought the horsepower rating up to 270."
Id say that a 270hp RS has your precious IROC-Z covered.

And pro the reason the mustang did so much better is because ford did a better job of delivering what the customers wanted. Stronger aftermarket for the crazy enthusiast and something that your non enthusiast could hop right into and be happy with.

I think its comonly over looked that the 5.0s were only faster in a straight line. And not all that much faster. With the 3rd gen I think GM concentrated alot more on handling. You can drive the wheels of these cars around corners. Especially the IROCs and WS6 cars.

Everybody who drives my car comments on how well it handles, they just don't like the fact my car is so low.

I have a LG4 with just headers, exaust and a holley 600 and i can easily put 3-4 cars on a 5.0 mustang. I even did it the other day with my carb giving me problems.

#2- I'm 99.9% sure not ALL IROCs came with 9-bolts. I know of a couple Trans Ams (not WS6's) that have 9-bolts. Either way a rear doesn't make a car faster (other than ratios which aren't all that different stock for stock).
85_LG4: You used to be cool man what happened. Calm down and chill out.

and when you compare that to a 9 bolt, the 9 bolt is far better
yea, i know some t/a's had the 9 bolt too, but i'm not too good on firebird history
and also, it's been awhile since i've checked thirdgen.org for the info
and yea, rear end makes no difference in speed, just clarifying some info

What is defined as a weak rear end? A friend of mine was in the car with me a few weeks ago when I decided to floor it from a stand-still. Spun like h*ll for about 8 feet and when I hit the white line the tires suddenly gripped and literally lifted the front end off the ground, tires and all. If my engine has enough power to do that, don't you think that I would have ripped my stock 10 bolt rear end out by 105K miles?

Are you sure you got the front tires off the ground? A mildly modified L98 doing a wheelie....I don't know.
A 10-bolt will hold up fine to stock/mild motors with an automatic. Manuals tend to put a lot more "shock" on the rear and that's what blows them.
