Callaway differences - a little help please!
The Michigan car looks pretty neat too

Comparing the 2 cars - they are about the same price, so that doesn't come into it really.
Remember this is MY scoring system - others may judge differently

- '87 has fewer miles (1-0 to 1987)
- '90 has aerobody (1-1)
- '87 has naca ducts (2-1 to 1987)
- '90 has more Hp (2-2)
- neither interior is great in terms of color, but both great in terms of condition (3-3)
I guess that means I either buy them both! or keep looking...
The LT1 and LT5 were "SuperNatural" cars that were not done through any GM ordering process. They are all aftermarket modifications.
The LT1 cars were all 383ci motors. Horsepower varied from 400-435. Things like the Aerobody were still available on these cars, and Callaway even made a wider ZR-1 aerobody for the SuperNatural LT5 cars (475-490hp from a stock displacement LT5).
While the SN LT1 cars technically have more power than the B2K cars were rated at, I don't think you'd find the driving experience as cut and dry. The B2K has a huge swell of thrust that comes on pretty early (plus the howl of two turbos), and then runs out of revs quickly. The SN LT1 feels pretty normal, in fact almost disappointing. It's not that it is slow, it's just so calm you barely notice anything. But I think that was generally the point with Callaway, the car was still civilized and there was no real compromise made to get another 100-135hp out of the engine (other than the cost).
On B2K cars, people have mentioned the main differences. The '87 vs the '88-91 is the main diff. '87's had NACA ducts, stock wheels, and IHI turbos. I think the turbos have proven to be cheaper to replace/rebuild over the years, I don't know if that is still true today. It also seems like all the higher miles/drivers are '87s. So if you plan to drive and enjoy it, an '87 might be more "proven".
The 4+3, ehh, no one really has much positive to say. But that's how all '84-88 manual cars are, what can you do. They seem to keep working as long as you are careful with the OD unit. The "4" seems pretty stout, it's the "+3" that has problems. If you buy one and it has problems, you do what anyone else does. Replace the overdrive, or put in a 5-speed or something. I'd take a 4+3 B2K over an auto.
'87s seem to be a fair bit cheaper than the '88+ cars. I'd think cheap enough that if you decide to go with a non-stock trans, who cares. It can't tank the value that much because it wasn't that expensive to start with. And anyone who plans to drive it will probably be glad the 4+3 is gone.

Yes, I was only interested in the B2K cars, the Supernatural ones were a little off topic (but interesting nevertheless)
So the 1987 Callaway's did NOT have the Dymags?
SurfnSun posted that the 87's could have stock, 16"Dymags or retrofit 17"Dymags....
The one on Ebay seems to have the stock wheels.
Absolutely agree - MUST be a stick shift!
I'm very mechanically sympathetic, but know of "rock apes" who can bust a transmission in anything
So the 4+3 prob won't be a problem for me, as long as it is in reasonable shape when I get it.Any idea on when the Aerobody first started being offered?
Was it available right from the get-go on the '87's?
Thanks for all the help guys, so far my watch list has crystalized to:
- 1987
- B2K option
- Aerobody
- NOT red or tan interior
- less than 45,000 mile
Any more info greatly appreciated
About 2 doz. 1987s had 16" Dymags. About the same number seem to have been retrofitted with 88+ 17" Dymags once available.
When the COG site becomes hosted again, you will fond a marketplace. In the meantime, if I can help further, just ask
I'm pretty new here.......who is "we"??
I'm also guessing to add the Aerobody wouldn't come too cheap either?
Would you need a full respray to get it to match the 25 year old paint?
You have me intrigued......

Here is the link for the Callaway AeroBody: http://shop.callawaycars.com/Corvett...84-1996_c4.htm
Figure the last one was about $16k by the time the car was repainted. Could be less, if the whole car isn't repainted

So the "Callaway" in your username isn't just for show
Must be cool gig, working there.
$16K isn't stupid $$ especially if you pick up one that needs fresh paint anyway...
$8.5K for parts, about the same for paint - quite reasonable really.
Given the quality of the rest of Callaway's work, it would be a top notch paint job, not a splash and dash.
found this in my research......
On Ebay in Florida for $25K or best offer.......

Did some back tracking and found it was sold on Ebay for $17K on July 20

Whilst I'm happy for people to try to make $$, a 50% profit is a little steep...

I guess it is Buyer beware

Here is another aerobody from the Lingenfelter collection. I visited their Michigan showroom this summer:
