I jus bout an 85 Camaro-It has the Z28 bading on the body kit and on the passenger side dash, but the guy bought it from swears its an Iroc-Z. How would i go about finding out for sure if it is an Iroc or not? what where the main differences?

HotRod55

check the RPO codes their should be a code for the IROC-Z option. I forget what it is, or you could find a RPO decoder and enter all your codes into it and you will know what options the car came with.

Welcome to TGO. LoRyder, a search is always a good idea, and as you can imagine your question is one that's asked with some frequency. You may wish to search a bit more, but the IROC came with 16" wheels and a Wonderbar, black headlight buckets, fog lamps, the quarter/rear bumper badging on an 85 reads Z28 (the dash badge, however, should include IROC-Z), the door decals should read IROC-Z and be positioned toward the front of the door. The ground effects should be the same color as the body. Check my Car Details below for a pic of an 85 IROC.

HotRod's right about the RPO. Check for B4Z, which is the IROC package.

Look in your RPO codes in the console box and see if you have the SPID sticker. It should have the RPO B4Z if its an IROC-Z28. If it also has the RPO 1C5 you have a "California IROC-Z28" which they only built 502 of in 1985 and is extremely rare since very few exit today in original condition. To be one of these it will only be in red or black paint. It won't have hood louvers, rear spoiler, no decal striping, or IROC-Z on the doors, if it is still original. It will have only 16" IROC wheels, fog lights, ground effects, LB9 engine, and automatic transmission if still original.

thanks for the quick responses-im picking up the car tomorrow so i will check it out then-it has aftermarket rims and no fog lights (which may have been because they were making a drag car out of it, i dunno) but i was just curious for basic knowledge

I assume if the fogs were removed, the correct grill would still be in place. The RPO may be your best bet. Here are some pics--hood louvres, badging, grill--that may prove useful:

now that you mention it-the holes are there for the fogs-i didnt pay that much attention to it-i just thought it was messed up and was thinking about putting the billet aluminum in its place, but if i get some fog lights, i may not be able to.....it does have the hood louvres tho, i just needa look at the dash badge and the RPO tomorrow-i appreciate the help tho

check the camaro web site.it will give you a certain number or letter to check on the vin number and that will tell u exactly what you have and the true engine size type and tranny

The way i usually check on the early ones is the door tag. If it calls out for 16" wheels then its an iroc. If its 15s then its just a Z. That doesnt work after 87 though. It could be either a base or an iroc with 15s after 87.

On that note, here is an important thing to check; the VIN # on the RPO code sticker, which is located inside of the center console.

I make many trips to salvage yards and always see the center consoles and boxes removed. The RPO sticker in your car may not be original. A VIN match will tell you exactly what you have.

IIRC, the vin will tell whether the car's a Berli or a sports coupe, but that's all.

The dash badge in my IROC reads only Z28 5.0 Liter H.O. I'm sure it is a real IROC because of the B4Z RPO and all of the other indicators. Were all of the L69 cars badged like this? Mine came out of the Van Nuys plant. I just noticed in the white book that it is stated that all Van Nuys cars had vins last six digits started with 500001. My last six start with 46.....! Is there a mistake in the white book or do I have a rare early IROC?

Best guess, yes.

This was recently brought up in the forum here. I think it was determined that the 1st 10000 cars came with the leading 46. Do a search for 85 iroc vin and see if you can locate it. It was within the past 2-3 months.

My car is a 1985 RPO 1C5 "California" IROC-Z28. The dash badge on mine and one other I've heard about only says Z-28/ Tuned Port Injection, under it with no IROCZ on the badge, but it does have RPO B4Z. It also doesn't have anything on the driver side rear bumper saying tuned port injected as other irocs do. Also the vin# of the 3 other 1C5 "California" IROC-Z28s I've located and mine all start the last six nimbers with 47, not 50. These were all built at the end of 1985 between May and July. My Camaro White Book,the newest edition through 2002 has the Vin# for 1985 starting at 400001.

My 85 L69 IROC has the Z28/IROCZ badge, in fact the GM parts catalog does not list a 5.0 Liter HO badge after 84, except it does list the 84 part # for 86 L69 regular Z28s! Since they only made 74 of those, most of which were race cars, I can't imagine seeing one! I'd love to see a pic of your badge! My car is a Van Nuys car produced 12/84, the last 6 is 419XXX. Are there any other 85 L69s on TGO?

Hank,

Check the following link, second pic all the way to the top in the first column:

https://www.thirdgen.org/forums/inte...sa-badges.html

Is that the badge you have (though difficult to see, it looks like Z28 above and 5.0 Liter HO below)?

No, that's not it. Actually it is the third one down in the first picture. I'm trying to include a pic in this message. Lets see if I can.
