Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I doubt anything will turn up... However you might try this... Go to ebay Look for a little white book called "GM Production Options" it is released by the Engineering department like this one : http://www.ebay.com/itm/GM-PRODUCTIO...69f0c4&vxp=mtr but from either late 1985 or early 1986, and there may be a chance, a slight chance that you will find what you are looking for... There is also a larger book that might be more complete, but I have never owned one of those.
Good luck

There are illustrations of all the combinations for every option by RPO and part number for interiors, body panels, wheels, stripes, paint colors, etc and what model Camaros got them from 82-92. It has information in it that I have never seen anywhere else.
I'll try to skim through it this weekend and let you know if I find Z5V somewhere in them.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Since Z5B is RPO for SEO override of MV4 for police & taxi, RPO Z5J is SEO override of RPO U25 for luggage comp, Z5T is RPO for SEO override of LM1 for police & taxi, and Z6B is RPO for SEO overide of RPO J42 HD brake, all letter-number-letter combinations, wouldn't it make sense that RPO Z5V is some other type of SEO override?

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
It has been over a year since the last post. So I'm bringing it up again to see if anyone might have seen or knows of any new documentation about what the RPO Z5V actually adds to the build of the car. This RPO Z5V and the RPO 1C5 are only on the 1985 "California Irocs". If anyone has any info would you please post it. Thanks and happy holidays.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
It has been another year and the post was back to page 11. So I thought I would bring it back to the front hoping some new or old member might have some info about the RPO (Z5V). I've owned the car for 9 years and haven't solved it yet. I also added some pictures of the car with an extra set of gold wheels on it instead of the silver ones that came on it originally. I still have the silver ones with the original tires. I took a picture of the engine compartment and noticed how stained the windshield washer and radiator canisters looked in the picture. I bought new nos ones a few years ago so I'm going to put them on today. Thanks to everyone for looking.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I took okfoz's suggestion and found the Chevrolet factory parts manuals for the 82-92 Camaros on E-Bay. These are put out each year and cover the previous 10 years. The manuals I purchased were printed in 1992 and go back to 1982. It seems to have every part used on Third Generation Camaros. It is 3" thick and lists every part number, break down diagrams of all the parts, along with the years any particular part was used or interchanged with other years.
There are illustrations of all the combinations for every option by RPO and part number for interiors, body panels, wheels, stripes, paint colors, etc and what model Camaros got them from 82-92. It has information in it that I have never seen anywhere else.
I'll try to skim through it this weekend and let you know if I find Z5V somewhere in them.

Did you ever look for it in the parts catalog? I ran across mine cleaning out the garage and was thinking of having a look.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I did look in the parts catalog and never found (Z5V) in it. Although, I did find many other RPO codes listed for other things that I have never seen at any of the RPO web sites on line.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Its Christmas time again and I usually bring this thread back to the 1st page from the 9th-11th page after another year of waiting to see if anybody has found documentation of what the RPO Z5V might be on my 1985 1C5 IROC. I've owned the the car for 10 years now and it would be a great present if it gets solved this year.
All my leads have been tried from GM archives to many suggestions by members and still nothing has been found. It just goes to show that accurate record keeping wasn't done on our 3rd gen camaros as were corvettes of the same era. If anyone finds something please post it.
No matter what comes of this search just have another good year enjoying your camaros as I always have.
Thanks once again.

This has become my once a year thing to do around Christmas time. I'm still looking for documentation on the RPO Z5V. If anyone has found some information let me know. Thanks

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Not exactly related, my son got me the book "Echoes of Norwood" for xmas. There is so much specific info it it regarding that plant, a lot of it from former employees, I had the thought that pursuing former Van Nuys people might be a good (if not only) outlet for your search. Just a thought!

The workers decided on a sleeper type of car that looked kind of "plain jane" without stripes or logos, no spoiler, which most of the muscle type cars had at that time, no hood louvers, nor other markings that would distinguish it as an IROCZ.
But, they wanted all the special mechanical features that the 1985 IROCZs could have like the optional (LB9) TPI engine, (G92) 3.42 gears, (J65)4 wheel disk brakes, along with the suspension features that came on the IROCZ that year.
They also wanted the ground effects, fog lights, and IROCZ wheels which could have been added by any owner of a V6 sport coupe to make it look as if the car was an "IROCZ want to be" clone. These features are what make a factory built car very unusual for its day.
The assembly line workers on this 1985 "Cali" IROCZ had a say in the type of car they wanted to build, given a choice, and they went for it. This seldom happens in large corporations of any kind!
It would be great if somebody that worked at the Van Nuys factory who were part of this historic build could give us more information. As you said above these assembly line workers would probably be the only ones who could give us any new information on this unusual car.
They would probably be the only ones that would know for sure if the RPO (Z5V) actually triggered the build for the "Cali" IROCZ which is what I'm starting to think versus the RPO (1C5) which was for the credit it received on the window sticker for deleted stripes, logos, spoiler, and hood louvers.
I have yet to see or find a build sheet on any of the 19 "Cali" IROCZs I have located. The RPO for the "Cali" IROCZ build order could be Z5V instead of 1C5 since all the cars I have documentation on also have Z5V on their SPID RPOs . I do have the Vin# of the 19 "Cali" IROCZs that I've located to date if anyone is interested. If you happen to own one please PM me.
Till there is some documentation from GM, or a build sheet on one we won't know for sure. Thanks guys

That's an interesting story, very cool.
Maybe this year is your year, and you come across some documentation. I'll keep my fingers crossed.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
It looks like you have a "California IROCZ" with the 1C5 RPO and Z5V RPO on your SPID. I have a list of the 20 others I have located by Vin# If yours isn't one of these that I already have I'll add it as the 21st one located to date. You listed your rear gears as 3.23 all the "California IROCZ" I have seen have the 3.42 gears. Do have GU6 on your RPO list which would be the 3.42 during that year. It also should not have G80 Posi on your RPO list since GM ran out of these around May 1 of 1985 and all 502 of these cars were made during the third week of May. They all came with an automatic transmission. Could you post a picture of your full RPO sheet or pm me and I can furnish you with a list of the others I have located.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I'm looking forward to seeing what else is on your car's RPOs and what order it was made in relation to others that I have documented. I hope that others that own a red or black 1985 "Cali" survivor look for this car with the 1C5 on the SPID RPO list along with Z5V RPO which confirms what you have. There has to be more out there especially in California, Nevada, Oregon, and Washington where they seem to turn up. Waiting to hear more about your car and others that hopefully show up, since most guys don't even know they own one till they hear about it, or see 1C5 on the RPO list like I did 12 years ago.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Your car has all the same options as my car which is red with T-Tops. I've noticed that the red T-Tops all had the same options, the red hardtop cars had different options than the T-Tops, but all of the red HT cars had the same options as other red HT cars.
As far as the black cars that were made with T-Tops and Hard tops I don't have enough information to know just what options the HT cars and T-Top cars had in common or not. If anybody has a black one let us know what options yours has.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Thanks for the full SPID with the RPOs.
Your car was made within 3 cars of another red 1C5 with T-Tops and identical options on my registry. This verifies that hard tops and T-Tops got their own specific options according to the type of top they had during a particular run of cars. Thanks for the documentation and confirmation of options. Yours is the 21st one to be found.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
My dad was the original owner of a 1985 Cali IROC. He recently passed away and we are trying to sell it. It is red and in good condition. He has the original window sticker that shows the RPO code of 1C5 which is a credit of $75. for California promotion credit. His car did come with a rear spoiler which is on the window sticker with a no cost. The RPO listed in the glove compartment shows the Z5V code. Does anyone know how I figure out what the production number is? Is it part of the VIN? And does anyone have an idea of the value of these cars? Thank you for any info

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Last night I spoke to the son of the original owner of this 1985 1C5 who had recently passed away. He sent me the RPOs and a picture of the window sticker. The D80 RPO for a spoiler that all other Z28s have on their RPOs wasn't on theirs. It also didn't have it listed on the window sticker as an option D80. He said that his father bought the car new with the spoiler on it back in 1985. They always just assumed the car came with it from the factory. They are now realizing with some research that the dealership put it on before he purchased it. They probably did it to help it sell since some dealerships had a hard time selling the 1C5s that didn't came with all the cosmetic features that the other Z28 IROCs of that year had on them.
I had a very enjoyable conversation with the person I spoke to about the car. He is also a real car enthusiast like most of us are on third gen. This is a genuine 1C5 California IROC and it is the 23rd one I have located. The Vin# is within 23 units of the next red hard top on my list. This verifies that certain models being HT or TTOP with the same color were made in batches at one time. This one is still original other than the owner had the original wheels chromed and the dealership put a spoiler on the car to help it sell. At least it is a dealer installed spoiler which might somewhat help or hurt its value. With 69,000 one owner miles it looks to be a very nice car.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Hello, I have an '85 Cal-IROC. My car is a red hardtop. I purchased it when I lived in California and is now in Idaho. I learn something every day. I did not know they made any with T-Tops. Do the T-Top cars still have the long overhead console? I have not read the entire thread so I do not know if someone mentioned there was an Cal-IROC article called something like, "Another Reason To Hate California" in a Trans Am magazine. I do have the magazine so I could dig it out and confirm the article title and magazine name if people are interested. I was the second owner and I do not have the original window sticker. The rear end was also replaced before I purchased the car around 20 years ago. The replacement rear end had gears in the 2.90 range which made it slow off the line, but could go ballistic on the interstate. I replaced that rear end with one from a 90'ish Trans Am with the aluminum disk brakes borrowed from the Corvette. The car was repainted around 15 years ago using the original DuPont Centurion Red paint so the under hood stickers are gone. If any one has pictures of the engine bay stickers, Emissions and Smog routing that they could share would be great. I found that the original spark plug gap was 0.045" and due to HEI coil issues was subject to a recall. The service bulletin called for the replacing of the emissions sticker with the updated 0.035" spark plug gap.
Regarding the Vokswagen commercial is really interesting. If the car is the Cal-IROC, it was repainted as the black door molding was removed. As someone mentioned, the front bowtie emblem was airbrushed out as it sits in a small rectangular recess which I could not make out in the video, but my eyes are getting pretty old. Great thread!

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I dug out the Trans AM magazine I wrote about above and found that it is the Camaro / Trans Am Magazine, Winter of 1985, Volume 2, NO.1. The article starts on page 42 and is about "OTHER IROCS." Basically, about the L69, manual transmission, IROC and the California IROC. The L69 was "removed from production two-thirds of the way through 1985 because of fuel system problems."
One more piece of the puzzle, in the Camaro / Trans Am Magazine article, it states that it was the Chevy California Marketing Group that came up with the idea.

I have been trying to find out what issue of the Camaro/Trans Am Magazine that article was published in for about 12 years. Good things do come to those who wait. I had heard about the article from other members here on third gen who remembered reading it years ago. No one could remember exactly which one it was in. Now I know what issue to look for on E-Bay or Amazon thanks to your information and I will do a search for it so I can try to find a copy for my collection. I've been able to find other rare articles about these cars during this time, but not the article you have in your hands. It would be great if you could scan the article in your magazine and post it here for all of us to read. Get some pictures of your car and most importantly the SPID in your console with the RPOs and post them too. It would be great to see your car on this thread.
Send me a PM with your Vin# so i can put it in my registry and I'll send you my list with the other 23 "California" IROCs I have located so far with their Vin#s we can see where yours was built along with the other Hard Tops. I want to add that all the T-Top cars that I have documented do not have the overhead console as the Hard Top cars have had. This goes to further verify that HT and T-Top cars of either red or black got specific options depending on the body style being built during a specific run of HT, T-TOP, Red or Black cars during that 3rd week in May, 1985 when all the 1C5 California IROCs were built. It must have been interesting for the assembly line workers to see a car that they had a decision in choosing the options on come by as they built the standard IROCs and Firebirds during the same day's work and batch run.
I have documentation of a standard red IROCZ being built 1 Vin# ahead of a red 1C5 California IROCZ during the same work shift, in the same color, so this shows that they were built side by side with other Camaros and Firebirds of the same color but with different build information (sheets) options and RPO codes. The V6 cars were even built right along with the V8 models if they were the same color. The paint color seemed to be the determining factor as to what was going to be built during a work shift at the factory. I own a 1988 V6 HT sport coupe in white that was built 1 Vin# from my 1988 TPI IROC convertible in white and I still own both. I bought these two cars years apart and what a surprise to find that they were built one after the other on the same day and run of white cars in Van Nuys, California. You never hear of this happening when millions of these third gen cars were built over a 10 year period.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Hello California IROC enthusiasts, I can't believe how difficult it has become to find the answer to the original post wanting information on RPO code Z5V. Now, for those who have searched high and low, here are some pictures of the pages from the CAMARO TRANS AM magazine about the California IROC.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I wanted to thank you rb3 for posting those pages from the Camaro Trans-Am magazine. I noticed that on page 43 there is a red IROC just above the black one. Is that also a California IROC in that article? It looks like it was cut off in the picture you scanned. If it is could you get a scan of it and post it too? I looked on e-bay and amazon for this magazine now that I know what issue the article was in, but couldn't find one for sale. I'll look each week and eventually hope that I'll find a copy of it for my collection. If anybody has a copy of it they want to sell send me a PM.
I've also been trying to locate another article about the 1C5 California IROCZ for many years. I have heard that it is in the Camaro Corral Bi monthly magazine 1992 January, February, March, April issue. Nobody I've spoken to are sure just which issue it is in. As far the exact year or issue I could be mistaken, but it is somewhere in an issue of the Camaro Corral magazine close to this year. Twenty six years ago is quite a while to try and remember an article that somebody once read about. So could you put your thinking caps on and if you have copies of this magazine see what you can find. If anyone gets any information about this would you please post it with pictures or let me know just what issue the article is in so I can keep looking for it. Thanks

Hello yo soy el warg: I looked back at the Camaro Trans Am magazine article I posted and the missing red Camaro is a standard looking IROC used as a comparison pic for the accompanying CAL IROC below it.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Hello 1C5 Cal IROC owners, Can someone can take a picture, or two, or three of the emissions stickers from their 1C5 IROC, I would appreciate it, mine are long gone and I do not trust the Spark Plug Gap and Ignition Timing info I have found.

I'll get to my car sometime this week and get you a picture of it.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
yo soy el warg, Thank you for the picture. I knew the after market databases were all wrong giving the spark plug at .045". In June of 1985, the original 1985 LB9 Spark Plug gap, Ignition Module, and Ignition Coil were all changed through a GM Service Bulletin issued in June of 1985 and later a Voluntary Emissions Recall Campaign in August of 1986.
The Recall gave 1985 L69 and LB9 cars built in Van Nuys with VINS from FL100001 thru FL456951. So the Service bulletin must have sparked the creation of the new Emissions Sticker for the IROCS produced just after the Service Bulletin was released, but before the 1986 Recall.
Now, I need to go back and compare the after-market data from 1984 (listed in the recall) through 1987 (when the bugs should have been worked out) as it relates to the "F" (LB9) Spark Plug Gap, Ignition Coil and Ignition module to make sure I have been receiving the correct ignition parts. Wrong parts could explain why I have been chasing a bad spark issue for the past several years. If I can find a cross-over for the original GM replacement parts listed in the Emissions Recall that would be a big help, but I imagine they may be lost in a long parts substitution list.
Thanks again yo sol el warg for confirming my doubts on the after market databases.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
More than a year has pasted since anyone posted on this thread so I'm bringing it back from page 13 hoping some new information might turn up. I'm on my 12th year of looking for information on these cars. I currently have the Vin# of 24 in my registry. Among these cars some still exist and others were stolen or totaled. I have information about some of the cars. If anyone has been lucky enough to find one of these cars PM your Vin# to me so I can add it to the list. If your interested in a complete Vin# listing and information PM me.
I'm also still looking for a copy of the CAMARO TRANS AM magazine Winter 1985 Volume 2 No.1. There is a post and pictures of one that a member has at #132 of this thread. I'd like to add one to my own collection. Contact me if anyone has one PM me. Enjoy the holidays and thanks.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
I haven't located anymore 1C5 "California" IROCs this year. I keep looking at various cars for sale ads hoping to find more of them to add to my list. I'm still trying to find any documentation on what RPO Z5V was for since it is on all the SPIDs of the 502 cars produced in 1985. Any information would be great. I'll post again at the end of 2021 have a good year. Thanks

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Thanks to daveb123 for bringing that 1C5 California IROC to my attention. They posted the Vin# on E-Bay so I have added it to my list. To date that makes 25 cars that have been Identified by Vin# and the 5th black car found. I noticed by Vin# that it was produced late in the one week run of these cars. I would consider buying that car but I currently have 6 third gens and have no space for another. Keep looking for more of these cars to add to my list, thanks.

Did you ever capture this one?

Also found this for a black car.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
Thanks Scott for the lead on the cars. I got the one that was advertised on bring a trailer sometime back in 2019 and just got that black one that is on E-bay this week. That brings the number to 25 cars located so far in 13 years of searching. There has to be more to be found so keep your eyes open. Thanks to everyone.

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
How many were supposed to have been made? I know for my 1989 ASC Firebird Convertibles I have found
109 of the 330 1989s.
19 of the 104 1988's
39 of the 173 1987's

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
There was supposedly 502 cars produced. Of this number supposedly 101 were black and 401 were red. The number of T-Tops and Hard Tops in each color isn't known. From what I have documented so far 5 have been black in color with 4 Hard Tops and 1 T-Top. There are 20 red cars that have been documented with 15 Hard Tops and 5 T-Tops. What's interesting is that the ratio of black cars and red cars found is identical at almost 5% of all those made in each color. The ratio of T-Tops to Hard Tops in each color is also almost identical. They apparently made more Hard Tops than T-Tops in each color. Years ago I talked to Dave Sauro who bought a black hard top new in 1985 and he said that the dealership he purchased it from only had Hard Tops in both red and black but no T-Tops. That seems to play out in the ratios of both black and red color Hard Tops versus T-Tops that have been found. I've noticed from the ones located so far that the black and red Hard Tops have the same options such as power driver seat, power windows, power rear view mirrors, split rear seat, and overhead console in all of them. Whereas the black and red T-Tops don't have the power driver seat, the power rear view mirror, split rear seat, or overhead console. With only 5% of these cars accounted for you would think there are more that still exist but haven't been found. Keep looking!

Re: What is the RPO code Z5V on my 1985 1C5 IROC?
The reason for my post is there was about 600 firebird convertibles from 87-89, and of those I have so many cars which I have verified over the years. I am surprised more California Iroc’s have not been found. Granted the ASC convertibles are more easily searchable to find.
I wonder how many Californias have been modified with a standard Iroc hood and spoiler. Even possibly when new.
they are very cool cars...

Howdy, I'm the guy that bought the one on eBay and guess I missed this thread as been focused on getting the car running - https://www.thirdgen.org/forums/tech...rage-find.html
Doing everything I can to keep it original and using NOS parts. Great forum as everyone has been really helpful and friendly.
