I have a friend with a 1990 IROC fully optioned with t-tops and a 5.7/700R4 combo. From what I have read off the web, the t-tops were not an option for 5.7 IROCs or Firebirds in year 1990....yet his numbers match. Can anyone shed some light on what happened in this instance?

 

Have you checked the RPO codes for CC1? I had a friend who had t-tops, 350/AT in a 1990 Iroc, but I never checked the RPO codes to verify it was all GM. They were not the C&C T-tops as I have a Trans Am w/ the C&C T-tops so I know what they look like really well.

 

For the 1,000,000 time, T-Tops were available on all 350 cars form 87-90 Camaro and Firebird

 

Hmmm, so you could get T-Tops with a 350, but you couldn't get a 86-92 convertable with a 350, right?

 

It is possible to have a convertible with a 350, depending on how the convertible conversion came about in the first place. ASC converted cars that were both designated as convertibles, and cars that weren't. If the car was designated a vert from GM the sixth digit in the VIN is "3", and these cars were not available with a 350. Cars originally designated as a coupe, VIN "2", could have a 350.

 

almost true, unless you paid for the option the 350 (which i still believe it was only hard top cars ) it was only available in a hard top,,, t top and 5 speed cars were 305

Completely incorrect.

From 87-90 T-tops were available from the factory with a 350. I personally know 4 1989 L98 IROCs that ALL have T-tops. In 91/92 T-tops were only available with 305 or lower engine options.

In 91/92 there were aftermarket conversions however.

 

not to be rude in any way,,, but ill have to go to the book for this one

From my understanding 90 was the first year no 5.7 and t-top rule started.But I have seen trans ams with both T-Tops and 350.

 

My 87 IROC has t-tops and an L98. RPO:CC1, L98. On the other hand my 87 GTA and 88 GTA were both L98 cars but neither had t-tops. I think it was alittle more difficult to get t-tops and an L98 in a firebird for some reason.

To use the terms of another member:

"For the 1,000,000 time, T-Tops were NOT available on all 350 cars from 87-90 Camaro and Firebird. They were available, from the factory, on all 87-89 Camaros. I don't know the detail on the firebird. Check your friends RPO codes for CC1 and L98. He might actually have CC1 and LB9.

 

Sorry if I didn't make myself clear. 1990 through 1992 are the only years I'm concerned with. According to GM sources and internet sources, model year 1990 and newer Z28 and Trans Am's both could NOT be ordered with a 350 if you wanted T-tops....yet my buddies 1990 IROC with a numbers matching 350 has them. Now I know it's a 350 because we have rebuilt it. The sources claim, despite already having 350 in T-top cars in earlier models, the chassis was prone to flex. Could have been because the HP and torque went up in 1990.

Now I'm not familiar with the C&C T-tops. Is this an aftermarket company doing work for GM, similiar to say SRP? I will have him check for the CC1 RPO code. If it doesn't have this code, can I assume C&C did the work?

 

ill get the results as soon as i can find my book, it shows options on every third gen made and exactly how many of each type ( t tops, motor, verts, hard tops, color combo's ect) havent seen it in a while ,,,however, when i find it ill do the research

The only cars that could have t-tops and a 350 between 90 and 92 were the Formula.

 

There are always 'strange' exeptions though...

Yeah....that's kind of what were thinking. I have seen other's who have posted combinations that were not generally available except for dealers. Maybe making this car more valuable.

 

I would probably say that the car has the C&C tops in it. Does the tops have a trim piece infront of and behind where the glass would sit? And how wide is the section of roof behind the windshield?

 

This pic is from the Camaro White Book page 120. As you can see all the 5.7 B2L's got the G92 option, and only available with IROC coupe.

CC1 not available with G92. Also note, not available with 5 speed manual trans. So the only 1990 IROC's out there with T-Tops from the "Factory" should only be Automatics with an LB9 (engine code 8th digit of VIN# F).

 

I was always told that 5 speed + 350 = NO T-TOPS.

I'm sure there might be some "freak" car out there that has it by mistake

 

Although the camaro white book is a good source, even the editor/author state that it may not be 100% accurate - I personally find that it does have many 'holes' and at time leaves the reader looking elsewhere for info - especially for the rare thirdgen cars like the TTA, B4C and 1LE's. For the first and second gen cars I find the info is much better especially since a lot more research has been performed over the 'extra' years the cars have been around. I can't comment though about its accuracy for the fourth gen cars.. Just my

 

NO its was 350 =No T5

But I thought it was 91 that started with the No t-tops in the 350.

My 87 Came factory with T-tops & 350

 

Those of you who guessed C&C....congratulations! You are exactly correct. Very cool. Thanks for the very interesting reading and enlightenment.

Where can I learn more about C&C? Are they still around? Another interesting option on this car is a dealer installed cell phone. Very antiquated by todays standard. Huge receiver box in the drivers side rear stowage.

One more thing....my buddy is concerned that he might have ruined the value of this rare piece by installing subframe connectors. Opinions....?

 

Ruined the value in the eyes of a collector perhaps, but increased it in the eyes of us enthusiasts!!!

Now he has the best of both worlds, the higher powered 350 along with the t-tops without the body flexing, creaking, and moaning that most of us with T-Tops and no SFCs have to live with.
