I traded my 1980 Z-28 for it. I really love this car still smells like new. Runs perfectly. unmolested.
BTW I didnt see a FNG thread. Hey I am new.

Yes it was repainted as the original finish was faded, god bless texas.

I am getting decals, if you can let me know where the best place is to get them it would be appreciated

welcome ,,, 30000 miles damn!!!! wish mine had that lol looks clean

 

Its an IROC time machine. Literally like a museum piece. Factory stereo sounds amazing. Smells new. crazy

 

Nice! Welcome.

 

Thank you, where can I get a list of RPO codes?

 

Why are the decals missing? Repaint? I did not think the decal delete option was available until 1988.

 

i bet it does ur lucky to find one of these well u will find some of these with low milles but the prices are way up there lol

 

Yes repaint, the PO had poopy birds and sappy trees.

 

Should be a sticker inside your center console with all your codes.

 

Got that took pics. was just wondering what they all mean. Was also wondering what the G80 gave you,

 

All your RPO questions should be answered here:

https://www.thirdgen.org/rpodecoder

 

it looks great! i like that color too. As for decals you can purchase them from Phoenix Graphix www.PhoenixGraphix.com

 

BTW, if the PO still has the original factory muffler/tailpipe assembly, I'd like to buy it.

 

Wow that is a beauty! Congrats on the great find! Welcome to 3rd Gen. Love the color, does it run like its new? Dash pad is mint. Would love to see the 1980 you traded.

 

Welcome to the board! Nothing like the feel and new-car smell of a low mileage, well-kept original. Nice color, nice options on that one. Now, just get the damn stripe kit on it and the purple tint replaced with some beter quality tint, and you'll be good to go!

 

Very nice 85. A little jealous at the condition of yours since I have an 85 as well and has no where near 30k miles.

 

Stripe kit will be going on as soon as I get some recs from you guys as to where to buy it from.

Also where can I get the measurements for the application?


Will techron hurt this motor?

Will K&N filters mess with the MAF? The PO installed some and I am not a big fan.

 

AH what color of stripe do I get?

YIKES just did the decoder and it says my stripe kit should be 86A Red and gunmetal

 

Then your car wasn't blue originally...gunmetal and red = white body....

 

well after some research it appears the that particular stripe code was a mess up from the factory as the Color codes are 30U and 30L for the paint (blue). I did some research on this board and there are several members with the same marking on the RPO listing......GM did change up the codes on some years.


Here is the thread:

Hello matt1970pon!!

RPO codes do change their meaning sometimes, and the "up to date" code 86A today could mean red/gunmetal, but when the code was used in 82-89 (based on my parts manual) it was Lt Silver/Black which matches my car!!

As for the G92, it's funny because, GM3 denotes the 3:45 axle ratio, not G92, G92 was just a marketing RPO that told you/GM that you had the performance axle ratio!! I had the 3:45 axle but, long story made short, I didn't get it when I bought my car in 1988, someone else got that part!!



P.S. I just checked out another site's decoder, and get this: 86A Stripe Color Accent, Two Tone, for a 1993 is Raspberry/Black, and for 1991 is Red/Gunmetal, yet they both have 86A!! Proves my point about the change up, so your 1987 IROC 86A is Lt Silver/Black like mine!!

 

You have gray wheels and a black interior. So you should have had silver/black striping and silver IROC-Z decals originally.

The best place to get them is Phoenix Graphics.

 

YUP, just ordered them. Thank you very much for the referral

 

G80 gets you "limited slip differential" or positraction. Glad to see that you did some research on the color stripes. Most people don't. GM reused the codes when the model that it was on, didn't use it anymore. This car should have the black and silver stripes, with the silver on top and the IROC-Z door decals towards the front of the doors. The stripe package comes with the correct placement for the lower stripes, but I'm not sure of the door decals having a placement guide.

 

Very cool! I love that color blue. Can you post a pic of your rpo codes. The decal delete option came out in 1985 on the California IROC. https://www.thirdgen.org/forums/hist...-code-z5v.html

 

Very nice car! I think it's unusual to see that color combo, most of the blue cars seem to have a gray interior. The blue cars could have had the black/gold striping, but they would also have matching gold inserts in the wheels, so obviously you're correct that the original stripes were silver/black.

 

the worst part about this car is the rubber hoses etc esp the pvc hoses is rotted, my sway bar end link bushing shattered, I have new ones to put on . Rubber doesnt do well after 26 years



By scotiapilot at 2011-12-07

 

You have 3.42 gears and a posi rearend. Nice options to have.

 

Just to be "technically" correct, there was no decal delete OPTION until 1988. The limited run of California IROCs came standard without the stripes. And without the rear spoiler. And without the Z28 hood...

 

Congratulations on a really nice IROC. On the repaint whoever did the work not only removed the stripes but they also removed the RPO-B84 body side moldings. But then there are many that don't like them except for orginality. As has been mentioned said stripes should be black/grey given the wheel accents are grey,the black interior and the rocker emblem are black/grey. It's interesting that heavily optioned car doesn't have t-tops. You even have rear discs,pwr antenna and mirrors - very cool.

This IROC reminds me of the one that sits in a yard about 10 miles from where I live (been there for over 10 years). She sits behind a fence and there's never anyone home.

 

I noticed that, what type of side molding is that? Is it that big thick rubber and revets stuff?

 

I hope you can bring it to next year's roundup!

 

30K miles I have put on 180 miles on her since we picked her up tuesday night.

The front end rattled horridly, seem the front sway bar end link bushing had dry rotted off. I replaced them this AM. and OH MY LORD this thing can handle!


MOST IMPORTANTLY: the shifts were soft and only shifted at 4400 rpm. No second gear scratches nothing. I just figured it was old and thats what they did.

WRONG!


I reset the the TV cable correctly and OH MY GOD this thing turned in to a hard shifting 2nd gear tire burning beast. WOW! it gets sideways in 2nd!

It made my day!

 

MARK! hey from NTTGA! Hell yes we will be there.

 

awesome! I'm uploading pictures from last year's event to the website now, but our facebook page has them already, so if you're on facebook, don't forget to go click "like" so you get notified of all the details of next years' event

and welcome to TGO (and NTTGA)

 

I just "liked" it and hit me up for for a friend request I am listed as F. Trey Ordonez

 

I believe your '85 would have the one piece rubber (urethane?) body color style to go with the softned lines (plus it was easier to install in production). My '83 has the two piece riveted style.

 

I need to look for pics then.

 

Your IROC-Z chirps 2nd? What condition are the tires in? Strange for a stock car, especially one without G92. You do have 3.23s though, which aren't that far off from the 3.42s. Yes, they do handle very good.

This is a nice car but it will be so much better with the correct stuff on it. I know you ordered the stripes and decals but don't forget the Tuned Port Injection ones for below the Z28 emblems. You should also get the rear bumper TPI emblem, Classic Industries or Hawks probably has it. The bodyside moldings on this car in 85 would have been the thin style in black, not body color. IMO, I'd leave them off, just be careful!

 

I was mistaken then on the body side moldings. What year did they go to body color then? And I forgot about the TPI decals on the rockers.At least they are easier to find than CFI decals. Mine are in good shape but bought a set off ebay a few years ago just in case (hope they hold up).

 

All of it has been ordered,


It doesn't chirp second gear, it spins the tires and gets sideways.
They are new eagle hp tires

GU6 is 3:42 gears btw
G80 is locking diff

 

Yeah, he does have 3.42 gears. Has the GU6 option. I orginally thought these gears only came with the posi in 85 but Charlies is non-posi and also has 3.42 gears. Apparantly, most of the 85 Camaros did. It is turning up to be more common in 85 then I orginally thought.

My father's 85 TPI will also break the tires loose and kick the car sideways in second. 85 IROC and 85 TPI Z28's are secert performers.

1. Hotter TPI camshaft (same spec as the 87 350 tpi cars)
2. 3.42 gears
3. More aggressive shift pattern in the trans.

Don't be surpised if an 85 IROC with the above could clean up a stock 350 TPI car since most of those cars were only packin 2.73 or 3.27 gears and the lighter shift pattern in the trans.

 

Ah cool, maybe that's why then. Weird that it doesn't have G92, 85 is a strange year in some ways. I wish those gears were available in the 9-Bolt. My IROC-Z would do the same when I first got it all stock, but it's an L98 with 3.27s and had pretty worn tires at the time. Since it's a faster and more powerful car it's easier to see I guess. (only 10 HP difference but 55 lb.ft. more TQ) When I had the tires and TQ converter changed on the same day it never did it again! The only other stock Third Gen I've heard of/seen do it is my friends 92 Z28 L98 G92. If I had to have an automatic 305 IROC-Z I'd probably want an 85 G92.

 

Beautiful IROC-Z!!! Not sure if anyone ever answered your question about the k&n filters, but no they won't hurt the MAF, I ran them on my '87 Z-28 never had any issues (I owned that car for 4 years). I have them on my '91, but it doesn't have MAF (I've owned her for 10 years now and God willing she's not going anywhere). I've never used techron, but from what I read on their web site sounds like a really good product.

 

I think the G92 code- "Performance Ratio" was only used on the 9 bolt rearend equiped cars. 85's have 10 bolt rearends so no G92 code. You had GU5 code for 3.23 gears and GU6 for 3.42 gears.

I am sure Scott knows for sure if I quoted this correctly.

 

Here is an 1985 B4Z with the G92 code listed on the spid. As you can see it has the same options, Gu6 G80 J65 even the same springs, 8NN 9NN 6Zw 7ZW it just dosn't list the G92 code on the spid.

 

Ok, now I am really confused I cannot figure out when they use G92 and when they don't. But who cares if you know you got a posi and 3.42 gears.

 

nice find put up some more pics when you get all the decals on

 

I wonder if its the dif of it being built at another plant

My car was built in Van Nuys, still has the stickers on the inside fenders that say van nuys

 

which one of you animals have put decals on these cars? have any tips?

 

The G92 spid is from Van nuys.
