WTB : Black Iroc-Z
 

I am looking for a clean Black Iroc Z 1986-1989.
Either a 305 5speed or a 350 auto.
Under 60000 miles please. Must be in good condition.
Thank youuuu

Are you a member of thirdgen.org?

No i am not, should i check it out?

Sure. The IROC's are what is next and there are deals out there to be had. If you do not find anybody here with one to sell join that board for sure.

The history section of the forum is pretty good.

Good review of the car here:

FWIW they did make a 1990 IROC though they were only made through December of 1989 as that is when Chevrolet's contract with IROC ended.
I graduated high school in 90 and many days were spent dreaming of ordering a black with blue/silver stripe 1990 IROC 1LE 5spd....

Recently sold a 1991 Z28 5spd hardtop black over grey perf axle ratio - 100k miles NO Rust at all - well used - original VERY WEAK paint and needed carpet and headliner - sold it for $2000

The performance axle ratio cars are second best to the 1LE's in desirability.

I believe gm built Irocs for 1990. I graduated in 1991 and drooled all over the Grand Nationals, Irocs and GTAs. At the time i didnt have a pot to piss in. But man i could drink alot of Beer!
I would buy a nice 1LE or B4C if it came my way, but prefer a mint Iroc

How much do you want to spend - I have 3 1LE's?

I also have a black 87 IROC but I'm not selling that. https://www.yenko.net/forum/showthread.php?t=125997

That would be determined on the car in question. It would have to be a car i really want...and you have a Black Iroc!

On eBay right now:

Really nice car that is. A bit more than i want to spend on one of these cars. Why did no one drive such a great car?

Real nice. Was this car for sale here on SYC?

Rev-up Motors has a nice 85 - they got the good cam in them and the 8 bit computer.

Last one and this one is interesting.. tbi, non ac & non power.. Says its 8K miles but Im wondering if its not 108K..

Ok I lied.. One more.. :grin:

That car is really pretty strange. Other than the wear on the steering wheel & shifter I would tend to believe the miles although the original gatorbacks should still be on it. I would want to see the RPO codes on that one because it has no options at all on it (not even a rear defroster) but has the IROC package? Also has the GMMG chambered exhaust/headers so not totally stock either.

Notice the block off plates on the sides of the dash where the vents would normally go - very rare A/C delete dash.

Thanks for all the tips and help. Im still looking for the right Black Iroc.

no clutch pedal?

Really leaning towards a 5.7 auto.

The BEST of those years would be a G80/G92 performance axle equipped 1989 with the N-10 dual cat exhaust.

The most fun would be the LB9 305 5 speed G80/G92.

The G92 will include the "1LE" rear brakes and positraction, but then ALL 1989 & up f bodies with 4wdb got the larger rear brakes in 1989.

They did make a few 1990 IROC's, but it was a very short production model as they introduced the 1991 model style very early. The 1990 got the air bag steering wheel, certainly the rarest IROC made.

That is good info. I really like the bodystyle and Iroc attitude. I actually attended an Iroc Race back around 1987 at Nazareth Speedway, Pennsylvania. What a time

G80 was just the Posi Rear RPO, G92 was the performance gears RPO code and not all of the 89's got the N10 exhaust as it was phased in that year. The 89 & up cars that got the "1LE" rear brakes (larger, aluminum Borg Warner calipers) were those equipped with the J65 4 Wheel Disk Brakes package. The nice thing about ordering a L98 5.7 model IROC was that you got all of the good stuff with it - the G80 posi, G92 3:23 gears, J65 rear disc, KC4 engine oil cooler and the power steering cooler that was amazingly similar to the ones on the 69 TA's.

Not all IROC's were built the same, and unless you check the RPO codes, an LB9/Auto can easily be disguised as a L98 one - but they are vastly different animals. The LB9 in auto form was neutered with the smaller cam while the LB9 coupled with the 5spd (MK6 World Class T5 in 88 & up) got the same cam as the 350. The only exception here is the 85 models that got the Corvette L98 Cam in the LB9 and was only available in auto form. Those are great cars to own as they are responsive in auto form. Don't buy an 86 at all, it was the low point of the bunch with the awkward high mounted stop light & the smaller cam, no 5spd & no 5.7.

1990 is the shortest production year ever for the Camaro & Firebird starting in the summer of 1989 and ending on December 31, 1989 - there were NO 1990 Camaros or Firebirds built in 1990. 1991 model year started on January 1st, 1990 and ended in the summer of 1991.

The Ohio Plant agrees...

This is great info for all. Thanks guys for your input.

my brain fade, G92 is correct, any 89-90 IROC with G92 / N10 is the one to have, all others are "cruisers"

not true, you can have a 5.7 IROC without G92 and you get single exhaust/cats.

Because of the mid year phase in of the N10 exhaust, the early 89 F body cars (C & P) with G92 didn't get the N10.

however all Pontiac Formulas/Trans Ams DID get G92 with the 5.7 after the intro date, not true with the Camaros

FYI, ANY LB9 G92 5-speed will be the "good" one

Co-drove at many, many SCCA events with one of the "father's" of the 1LE, used to know part numbers upside down, time is a cruel thing ... :-)

This is turning out to be a great Thread

You are wrong here, ALL of the 5.7 cars got all of the equipment I listed above regardless if they included the G92 or not - it was all part of the B2L package.


Mid year N10 introduction bulletin for Pontiac.

The years were not mutually exclusive however - different years used different combinations of RPO codes. 91 & 92 Z28's with the L98 required G92 to get the 3:23 gears 87-90 did not. Shortages also caused the replacement of the J65 rear discs with the J41 drums in various years. 85-90 got the Australian built Borg Warner 9 bolt (the better rear) 91/92 got the 10 bolt.

It's a tangled web of inconsistencies and changes - when the OP finds a car and wants to check it out - let me know the VIN & I may be able to pull the entire RPO list for you to confirm it.

Not for sale but figured I'd post:

1989 IROC-Z. Ordered new by me. LB9, 5 speed, G92, (which bundled), N10 dual cats, 3.45 BW Aussie 9 bolt with the PBR brakes and KC4 oil cooler. It's also a DX3 decal delete car. 11K miles. For the record, the 5 speed LB9s got the L98 cam instead of the LG4/L03 "peanut cam".

If you wanted a fast one, you needed to know your way around the order book. There is a HUGE difference in performance between the "peanut cam" LB9, single cat exhaust, 700R4, 2.73 rear axle, disc/drum IROC-Z the dealer would stock and the one I special ordered.

I almost ordered it as a 1LE. By my intention was to use it as a daily driver and I was tired of going to work sweaty with no AC. Who knew I'd only have 11K miles on it 28 years later. LOL!

Wow, sounds like someone got a great deal!

Hey! I know you! :D

That Iroc is all business. Now get out there and drive it.

double post

Thanks! I seem to drive it less and less every year. I'm happy when I can run through a tank of last year's gas.

But I have two others that I drive.

My yellow '85 with about 43K miles.

And my white '89 'vert, 5 speed with 7K miles.
