how to find out if i have an actual "iroc"

I just bought an 84' and the guy keeps calling it an iroc, the title says its a 1984, and i know chevy first started makeing the iroc's in 85... so.. that leads me to the question, is this possable?
It says z28 on the rear bumper, but there are no "iroc" decals on the doors, just z28 everywhere, i know the iroc code is b4z, but im not sure where to look for it, and even if i understand that correctly, am i getting z28 confused with iroc, or what, whats the difference? I just want to know if i can rightfully call it in iroc and how i go about confirming its an iroc...
Thanks guys

your getting z28 confused with IROC...starting in 85 they were IROC z28's before that just plain z28's...same with the 91 and 92's there just z28's

The IROC wasn't avialable until Feb 1985....anything made before that was just a Z-28. The RPO codes are on a sticker inside the glovebox.
If the guy that sold you the car really thnks it is an IROC...he is an Idiot and should be treated as such.
The difference between an IROC and a Z-28 is very hard to see. But the difference between an 84 Z-28 and an IROC is easy to spot..the tail lights..The IROC's were in a "grid" pattern (1985 was the first year for the grid tail lights IROC and Z-28)
An IROC sits 1/2" lower than a Z-28 of the same year, they came with 16" wheels, Bilstein shocks and struts and a VERY tight ratio steering box Also the IROC had a 5500 RPM redline tach, while the Z had a 5k RPM redline.

Damn guys, thanks alot.. thanks for all the little added facts and everything also, im going to go out tomorrow and check in the box in the trunk for the code.. just maybe its there? lol

Z28 still kicks ass.

84 is not an iroc, just a plain old Z28. IROC became an option for the Z28 in early 85 (option code B4Z 85-87).

Just in case no one knows what IROC stands for its International Race of Champions

Are you sure it's an 84? Actually had a car (can't remember which one...) that everyone had listed as the wrong year. It was a vin issue... somehow they all got a wrong digit someplace... which was really dumb because I typed and faxed the number to the insurance company and all. The only number that was right was on the original title from the other state.

Also, if you look at the number of people on Ebay that have no clue what they are selling, or are just trying to cover up dishonesty with perceived stupidity, it's really astonishing. You can probably pick up at least 5 listing for a 70 camaro where it's really a 71-73.

That is clearly not a IROC nor anything '85 and up. The "skriting" was entirely different on the 82-84 z28. Lastly would be the dash emblem would read IROC as well.

from what i've experienced, people that are not f-body enthusiests like the majority of us here, refer to all 3rd gen's as "iroc's". If only i had a nickel for everytime some local would ask me "hey, do you still have that iroc?"

Why the big R and not the A?

Why the big R and not the A?good point, lol. see what im talkin about.

I don't have a clue what you're talking about. I'm just kidding with you....

1990 if I'm not mistaken was the only year in which the IROC-Z was an actual model... until '90 the Iroc-Z was (as people have said) an optional package for Z28 model Camaros. On the bottom skirt behind the front wheels were the Z28 badges and the large IROC-Z graphic was near the rear wheels on the lower side of the doors. You can spot a 1990 IROC-Z because those smaller badges behind the front wheels say IROC-Z instead of Z28.

Somebody once told me that the 1990 Iroc-Z's were the only ones ever to come equiped with factory true dual exhausts... wonder if anyone can confirm that???

85-87 the IROC was an option (code b4z) for the z28 and were the only years that it was an IROC-Z and the decals were toward the front of the doors and z28 emblems were retained. 88-90, the z28 was dropped (even though the RPO code for the iroc was changed to Z28) and the IROC (not IROC-Z) was a separate model. decals were toward the rear of the doors and emblems were changed to IROC. no third or forth gen (to my knowledge) has ever been equiped from the factory with dual exhaust, only dual outlets from the muffler. on late third gens, RPO option G92 included dual cats so maybe thats why u herd the roomer.
