This has been a long time debate here. You have the money you have whatever car you wanted Produced, maybe not, special order, possibly.

Chris`s85Z28

ok then if it`s an 8 then it`s a factory 350 car... so i guess they did have t-tops in 1990... DAMN... i know 90 Iroc`s are rare yours has to be REALLY rare.. thats some good news for you then.

There is alot of 3rd gen's out there with aftermarket T's, most can be identified easily as the front roof peice on alot are larger and the side peice above the seal is larger on most.

Run your RPO's to know forsure



1990 was the change over year with the rear's, some have the disc 10bolts others the 9bolts, I guess they were using up the old stock, dunno forsure but I have owned 3 1990's with 9bolts and 2 with the 10bolt

I did find a sticker from the company logo C&C Car & concepts ... dated back to 11-17-89 around the time this car would of been produced ... anyone heard of um ?

C&C did the T-Top conversions on many camaros and firebirds around that time. I think they also did the notchback hatches.

yea urs was special order then bc no stock car with a 350 had t-tops bc the torque of the motor would twist the car so much that the t-tops would shatter, also the other reason why no 350's came with T5's the torque would destroy them as well, thats why GM never put the 2 tgether. urs is really rare and u should be able to get more $ for it.

acutaly 1990 didnt come with T's and a 350 but 1987 did come with a 350 and T's

Stop. Stop spreading misinformation, stop abusing the English language, and stop neglecting the ability to type!

C&C did after market T-Top conversions for cars of most years. There were no "factory" T-Top 90's with 350's. The only cars with factory T-Tops and 350's are 87's, 88's, and 89's.

My T-Tops have never shattered, and my 350 loves 'em just fine. The actual reason they were dropped were concerns over body twist, as T-Top cars didn't get the same kind of reinforcements the convertibles did. To really do damage though, you'd need to have your foot to the floor ALL the time. Besides, you should get SFC's anyway.

Also, the reason the 350 didn't come with a manual wasn't because the torque WOULD destroy them, but it was a possibility they couldn't rule out. As far as I know a few members run a T5 with a 350. The real reason is that GM couldn't get the T5 warrantied with the 350 due to torque ratings. The 700R4 was rated for that much power, but no production manual was, rather than build a new manual for the Camaro, they just said no manual.

what did the vette's use for a manual shift during this time?

GTA Jim

L98 'Vettes used a T10 4 Speed manual coupled to an automatic overdrive system. The overdrive was ECM controlled and cut in automatically for 2nd, 3rd and 4th gears. It was called the Doug Nash 4+3 This tranny was only used in the Corvette.

In 88 or 89, they went to a German designed 6 speed manual.

T-Tops were fairly common in L98 cars up to 1989. I have a friend with a 1989 GTA that has an L98 and factory CC1 T-Tops. The Tops weren't dropped completely for 350 third gens.. After 1989, they got very scarce.. I don't know if any 1990 L98 cars came with factory T's ... They did offer T-tops with the L98 in certain 1991 and 1992 Firebird Formulas.

Several people are running 350's with the T5 without problems. Some others have blown 'em up. I'm getting ready to do the swap, but I can understand GM not risking it!!! ....my buddy has a stout 396 backed by a T5, now he doesn't drag race but he doesn't baby it either..., but it's been 2 years and he's just starting to have some issues.

I have an 89 350 with t-tops. In fact, check the classifieds and see how many people are looking for hardtop 350s to build race cars. I think they're actually MORE rare!!!

Also i would say that with GM anything is possible. I have had two third gens and one was an 87 IROC with every option except the engine oil cooler(atleast it wasn't on the car when i purchased it). When I tore the 350 apart I found that it wasa 4 bolt main block from 87. Now there is no way for me to know if this is the block that gm put in there from the factory because they had a surplus of 4 bolt blocks or if someone blew up the factory motor and replaced it. and I have an 89 formula that was origanllly a 305 tbi 5 spd. but has a 36mm front sway bar and came with the compact light weight spare tire. Also 1le cars or b4c cars could be ordered special and possibly with 5 spd. If you had enough money GM woudl build it the way you wanted or so it seems. Check the codes is the best route.

.....nope, not with the 5 speed. ...of course, that's not saying a dealer couldn't have installed one.

Probably. Not knowing past history is what skews reality, if you didnt buy it new and knew for fact everything was as factory delivered... replacement is always a possibility. Lot damage goes past just body parts sometimes.

I dont know about the spare offhand, but the 36mm bar came on all Formulas regardless of drivetrain.

And no amount of money and a good contact within GM were able to put a TPI in a G-body from the factory in 1986 so I dont know where all these with money or connections anything is possible stuff comes from. Extremely unlikely if not impossible comes to mind.
