I have a stock 5speed 88 IROC.

Someone told me recently that there weren't very many of these made. Is there a way to find out?

I also have RPO code 1AZ.

Does this mean it was a special customer ordered configuration?
Like the original owner went to the dealership and said I want this and that and a couple of months later it was delivered. Is that what this RPO code means?

You cannot tell the rpo combo's made but can do some number crunching.

There were 12,620 LB9 (305 tpi) engines made in 88 out of a total of 96,275 camaros made in 88.

Of these 96,275 camaros, 77,179 had the automatic trans which is about 80% had autos.

So you can probably assume that 20% of the 305 tpi's had the 5 speed which is approximately 2500.

This just gives you an approximate. It could be more or less but my guess it is around 2500 IROC's had the 5 speed 305 tpi.

Hope this helps!!!

Thanks for those numbers.

I have other questions now.

305 TPI does usually assume IROC. But what about the B4C and other places the 305 TPI went into like the California special non IROC(insurance thang)?

Does anybody know any other Camaro combo that tpi's went into?

There are some IROC's that did get tbi. Other than z28's and IRocs and the B4C's, those are the only cars that come to mind with a tpi option. I think the 90 rs convertible could get the 305 tpi option but none were ordered.

Do you know how many B4C's there were?

Did all B4C's become cop cars?

Does B4C mean TPI in a non TPI optioned package?

Thanks for all your help.

There were 592 b4c's in 91 and 589 in 92 made.

Not all b4c went into police service. Some were sold to the public perhaps about 30 or so per year, even though they were not suppose to. Alot went to state highway patrol depts and some went to the FBI, I heard.

Basically the B4C is a "z28 in rs clothing" Came with 145 speedo, oil cooler, 4 wheel discs, limited slip rear axle (3.23 for 350 engine and 3.42 for the 305).

If you need more info, let me know!!!

Did you use 91 and 92 as a refference or where those the only years B4C was an option?

FBI car? Now that would make for a cool signature.

So, about 2500 5 speed IROC's in 88. Cool!

where are you guys getting these stats. I want to know how may 87 g92 TPI 5spd Irocs where made in 87.

The stats don't exist for any option combinations. People can make educated guesses, but GM didn't work in linear ways. there are only official numbers for each individual option. You could find out how many Irocs were made in 87, how many G92 cars were made in 87, how many 5 spds, and how many LB9 or L98 cars were made, but you can't find numbers for any of those options combined except if options were exclusive.

I just wanted to add that even if you could get compound stats from GM, I don't think it would matter much as far as value goes. Look at it this way; If you had one of the 602 '67 Z28s produced, it would be a valuable, rare car no matter what the option content was. It wouldn't affect the value if it happened to have RPO AS1, shoulder belts(qty. of 477), because the car itself is already valuable just for what it is. Conversely, a dime a dozen '89-'92 RS would not be more valuable if it were equipped with a low production radio, as opposed to a higher production quantity radio.

Aside from an option that actually makes the car what it is (Z28, 1LE, B4C, etc.), I cant think of an example of when a car is significantly more valuable due to a combination of insignificant options.

Of course, I could be wrong.

camaro6spd

ummm...I though that the engine/trans combo with a performance package would not be insignificant(speling). Where can find these numbers out.

Drew

iTrader: (58)

In the Camaro White Book you can find numbers for how many Irocs were built in 87, how many 305 TPI cars were built in 87, how many cars had G92, and how many had a 5spd. But what it wont tell you is how many 87 Iroc's had LB9/5spd and G92.

I need to add too that published 1987 option figures are grossly incorrect. This was the first year that Chevy grouped option packages and incredibly, specific options that were included in these packages were NOT counted!! I hope Chevy learned a lesson on how not to count in 1987. Personally speaking, this is highly unfortunate as 1987 is by far my favorite year.

If anyone wants me to elaborate on this topic with specific examples, I will.
