Is this a Z-28 or an IROC-Z? 1987

I came a cross a pretty red 3rd Gen Camaro today, and got out and took a look. I don't know if I want this car right now, I am more interested if the dealer knew what they were talking about or if they were being straight with me.

I was told it was an 1987 Z28 (NOT IROC-Z) with 79,000 miles on it. They claimed it was all original, but I was not sure how long Z28's were made along side the IROC-Z's that started in 1985. Someone else posted that 88-90 were IROC-Z years only.

So WERE their non-IROC Z-28's made in 1987? I am thinking the hood should still have louvers, but it does not. Repaint? The interior is awesome, but I have never seen that sort of vinyl (red/black/grey does not say Camaro) in a 3rd gen Camaro before, and I am pretty "into" them, not a novice. They wheels look Z-28, not IROC. The back tail lights look IROC, and there is a missing decal, I think for "Tuned Port Fuel Injection".

Thoughts? Is it a Z-28 or an IROC repainted/rebuilt? If Z-28, does it look original from the pictures? How about my comments about the interior?

Thanks for any info you can provide!



I have been so involved with my IROC's, I have not kept track of what the Z-28's of that time looked like.




Is it a Z28 or not a Z28?

Both Z28 And IROC-Z Were Available In 1987,From The Pic It Looks Like A Z28 Also Looks Like It Was Repainted. Check The RPO Codes To Make Sure.

That's a Z28. All IROC-Zs had the fog lights. The 15" wheels shown were also Z28 only in 1987.

Re: Is this a Z-28 or an IROC-Z? 1987

The dead giveaways are the lack of foglights, 15" wheels, and the biggest one - the silver ground effects. All Irocs are monochrome. The fog lights were available on the Z28, but they were optional.

I wouldn't bet on it being a repaint. Most of the time when a Z is repainted, they aren't going to take the time to paint the gfx a contrasting color. The door guards don't usually survive a cheap repaint either. It does look like someone removed the lower stripe decals. The Z28s from 85-87 have a very distinctive stripe decal all way around the car just above the ground effects. Could be an indicator of a repaint, or someone just removed them because they're huge and somewhat dated looking.

Looks like a nice Z28. Can you provide more details about your comment it has vinyl interior and no hood louvers? My guess from the photos is it has cloth custom interior (low back seats), and of course hood louvers. Just curious. Not important. Thanks.

RPO code in console would have B4Z for IROC Z handling and appearance package, and Z28 dash plaque should say IROC-Z at the bottom for an IROC Z.

Door/side guards on an '87 should be body colored, therefore those on the car now were added and/or replace originals.

Re: Is this a Z-28 or an IROC-Z? 1987

I just thought hood louvers were standard on all Z28's and IROC's of that year.

I think the interior is not standard. I should have taken pictures, but I did not. They are vinyl look, possibly leather. I do not know of any standard vinyl or leather interiors for those cars in 1987; that is why I was hoping someone else might know. They are 3 toned, real sharp for a red car with the light gray carpeting: grey/black with red detailing, no writing. They are the exact shape and dimensions of the original interiors for these cars, so I suspect they are made specifically for 3rd Gen vehicles. I cannot find a picture on line that looks like what I saw. If I get by that way again, I will try to take a picture of the inside.

Also, I forgot to mention I think the speedometer went up to 140. Is that normal for a 1987 Z28?

Also, if I do get up there again, (I feel myself being pulled), what is a quick, easy thing I can look for to be able to tell whether it has 79,000 original miles, for 179,000 original miles?

Re: Is this a Z-28 or an IROC-Z? 1987

About 20 years ago I bought a 1987 Z28 that looked just like that! The car had a rod knock & a few dings & dents when I bought it from a local car lot. It was loaded with all the options. T-tops, EQ radio power seat, mirrors, power assist trunk, etc. It had every option but leather & the Iroc package. (not sure if you could even get leather in a Z28) ?

Anyway, when I repainted & rebuilt the car, I cloned it into a 5.7 Iroc for personal preference & I used all the parts & fog light wiring harnes from another legit Iroc in a salvage yard. They were plentiful at the time. I later sold the Z to a friend of a friend & the buyer knew exactly what it was. Now that I am so into originality of these cars I often wonder if that car is still out there, & if the subsequent owners knew it was a clone? At the time I thought nothing of the change, today I would have left it alone. A loaded Z28 would be harder to come by than an Iroc imo. The car would no doubt be a buyer beware car because it completely looked correct other than a 5.7 callout in an "F" car. (and missing the rpo code of course)

I have picts of the car in an old photo album but not sure if any showed the interior. I never took interior pictures of any of my cars back then.

Didn't all of the 1987 Z-28's come with the LG-4 Computer Carburated Engines and the IROC's with the LB-9 Fuel Injected Engines?

My 87 Z28 had the LB9. 99% sure it was original to the car.
Maybe this was true with 85 or 86 Z28's ? just a wild guess on my part.

All 1987 Z28s came standard with the LG4. other engines were optional. The IROC-Z package was also an option on the '87 Z28
