IROC Questions!

These are a bunch of questions I have concerning the Iroc...

Which Iroc is more valuable, the 305 T5, or the 350 700-R4?

Which Iroc year is the most sought after year, what year were the Iroc's the BEST!!!

Did Iroc's have the option to come with Louvers?

Is there some sort of option for black wheels? Or black trimmed wheels?



I will ask more, when these are answered...

-Thanks

it depends on your preference some like the stick shift but you dont have the power of the 350 it all depends on you. 90 is considered the most sought after because its the last year also different dash and airbags. in 87 you could get the 350. if you mean the hood louvers?? i think thats what you mean then no there were factory on all irocs and z28's except the 91 and 92 z28's i have a 92. i dont think black wheels were a option??

No, I meant rear window louvers...

Ok well how rare would a double black (Paint and interior) IROC be with a 350, any year...

i dont know bout the rear window louvers ill try to find out for you . ill check and get back to you. also it depends on the year for how rare but the 350 didnt come till 87 so 90 with a 350 would be the rariest in colecter terms. also the the double black is pretty rare and a great combo very hard to find. i would spend alot on one

The best IROC would be an '87 with a 350 if you're wondering... because it has the nicest wheels and was available with a 350

There were tens of thousands of 350 cars made so the type of rarity we're talking about has a marginal effect on value... at best they're more unique and more desireable.

I think the louvers were installed at the dealer though.

As far as being valuble, I think any IROC with a T5 and in good condition is going to be valuble becase there weren't that many built to begin with and a lot of them have been beaten on pretty hard. '85's and '90's are probobly more valuebule/sought after because they're the first and last years of the model. Silver or yellow IROCs are pretty rare, as they were only availible from '85-'87. Orange or gunmetal grey 88's are pretty rare too. I'd say the '88-'90 1LE's are probobly the best, rarest, and most valuble IROCs though, assuming you can find one.

I have heard it said that 87 is probably the most the most desirable year. There are many reasons for this.

1. 1st year for the 350
2. 1st year for leather option
3. last year for Norwood
4. 1st year for new paint process
5. 1st year for option packages
6. Only year that all performance options mandatory with the 350
7. 1st year for Bose option
8. Last year that Z28 and IROC-Z were available together.
9. TTops and 350 available together

Line 8 above is a kicker with collectors. Since the B4Z option was built on top of a Z28, It was considered the ultimate Camaro. Granted, it can be had with a base LG4 engine, but the 350 optioned 87s, are at the top. I would think that a comparably equipped 87 IROC-Z with the LB9/T5 would share the same collectible status. In 88-90, the IROC-Z was the only performance Camaro, but was available with base options up to top of the line. It, as a model, was no longer the top of the line car until it was optioned that way.

1990 is a good year for collectibility, bu there are too many things about the 1 year that make it hard to determine it's value. It was a short model run, no ttops with 350, new airbag standard, Speed Density. It was the end of the IROC-Z, but not the end of the 3rd gen run. That's why 92s appear to be more valuable. It was the end of the run. If 1990 was the end, the 90 IROC-Z would be untouchable.

Now, for those that are thinking I said the above because that's what I own, you're wrong. When I bought my car, I had no idea what I had. I got lucky. I knew I wanted ttops and a 350, but didn't know all the details regarding the 87 until I shopped TGO. I almost bought an 88, but the deal fell thru and this was a last minute find not far from my house.
----------
Also, rear window louvers were a factory option starting in 86.

My crystal ball says 350 auto's will be worth more. There is no replacement for displacement. The majority of people that like shifting a 5spd, are the young folks. Young folks don't got money.

I like the 350 cars just because of the power... I like driving standard cars too, but most of the people that think they prefer 5 speeds in all conditions probably have never driven a properly modified automatic. I used to have the standard or die philosophy until I bought a big block with an automatic, now I'm more of a 5/6 speed for twisties and an auto for straight line and cruising. 'Course as the years go by I'm getting the feeling that "youngster" doesn't really apply to me any more...

An un-altered car is always worth more to a true collector, no matter their pedigree.

But all pedigrees are not created equally, even if they are un-altered. So you'd still have a, "what's more valuable" situation.
Example; what's worth more to a "true collector", an un-altered 1LE or a base model?

Of coarse, if you don't compare pedigrees and single out a particular model (all things being equal), the un-altered ride will usually fetch more $$$. Unless the modified one has absolutely over-the-top changes. Like taking one through Jay Leno or Chip Foose's garages, etc. Then you could still have exceptions.

Abubaca, you're just jealous your car isn't an 87!!

Louvers became factory options in 86 and were available until 92.

I know this was after they ceased production on the Iroc but didn't they hook up a six speed to the 350 in 1991 or 1992 and no I am not talking about the limited production Firehawk.

I believe they were considering adding a 6-speed towards the very end of production of 3rd gens but never did, waited until the 4th.

I have seen pictures of 92 camaros with 6 speeds but don't know if they were mules, production cars or aftermarket

The police cars got six speeds in 1992 maybe some of the pics i saw were converted police cars

I believe you just contradicted yourself. I got that info about the police cars having 6 speeds from this website. Anyone want to shed some light on this????

If you're referring to the information for the 1992 Camaro in the Tech Data section, what the poorly worded text says is that the 25th Anniversary Edition Camaro was to receive the B4C package, and then be upgraded further with siamesed intake runners, headers, GTA wheels, and the ZF6 6 speed transmission. This package never went into production. Only 2 prototypes were built, and only 1 survives today.

The text is not saying that all B4C cars received the ZF6.
