I am wondering wat would be faster. I know the 92 has a little more power but i am not sure about the weight differences. would this just be a drivers race or is there a difference? Also were t-tops available with a 350 in 87?

 

wow nobody knows? If u do get those posts up here!

 

I'd go with the 92 and 245hp.

 

Apparently no 350 cars left the assembly line with t tops, but supposedly dealers could get them converted. I've never seen pictures of a 350 T top car. Same goes for the 350 and convertible debate. None left the assembly line, but supposedly some conversions have been done.

 

i think 87 there might of been ttops cause check this out

i have seen a few others too.

 

Do NOT use ebay as your frame of reference. So many people try to pass off LB9s as L98/B2Ls it isn't funny. Unless you see the block casting # in person you cannot tell if it is a "real" L98. Like I said, a 350/t top car is theoretically possible.

 

I would go with the 92 car. No T-Top cars available with the L98 in 1987. I believe they came available sometime in late 1988. I know for sure you could get a L98 and T-Tops in 1989 as I bought one and still have it. I believe they were also available in 1990.

 

Well the '87 L98 produces peak torque at 2800 vs. other years 3200. I think 87 used different cam than every other year.

yes the 350 came in a t-top car till 91. you can't find a 91-92 with a 350. click on my cardomaim and look at the blue stunt car. I was and 89 with the 350, and t-top. Vin matches.

 

nice stunt car. how did u get a hold of that? thats a good movie btw.

 

I just noticed the L98 350 issue about t-tops. My car had an L98 fron the factory and I have factory T-tops. T-tops were only available on L98 in '87, '88 and '89. Also 5-speed tpi 305 1990-92 cars could not have T-tops.

 

you could get an iroc with t-tops, they had issues with the body and later decided not to go that route with the 350's in the 91-92 camaro only cars. the pontiac versions had them all through the thirdgen years.

as for faster. the 92. especially if it had the smog and a/c delete but even stock for stock the 92 was and is faster comparing equally.

 

You can get t-tops. in 90-92 but not in G92 and TPI 5-speed cars. All L98 cars had G92 just for clarification of my earlier post. Thats neat to know about the T/A's having them all years.
Also, for some reason the fastest stock IROC recorded 0-60 was the '90 L98. It was 5.8 to 60 from a stop and did the 1/4 in 14.4. It's shown here http://www.albeedigital.com/supercou...0-60times.html I used to have the magazine back in 1990 but cant remember which one it was.

 

My '92 L98 ran a 5.4 0-60 and a 1/4 at 14.2 when it was totally stock with 108K miles on it.

 

is it possible to have a non ttop car converted to having ttops by an aftermarket shop or maybe a dealer. i know u could back then by the dealer but i am guessing u cant anymore right?
