I not familiar at all with C4s, and neither is my coworker who just acquired a 1987 corvette coupe that was willed to him by his uncle. He is under the impression that it is a twin-turbo Callaway. He's also been told it is 100% all original. Here's the kicker: its an automatic. I've read that all Callaway's came as stick shift, which leads me to believe either:
a) This is not a Callaway
b) Its not all original, and someone made this into a Callaway-esque clone.
Could you guys fill me in on how we can tell if it is a Callaway (VIN, equipment, etc)? Thank you!
Does the car have the Service Parts Identification sticker, sometimes called the RPO list, under the console lid??. If the car was ordered through a Chevy dealer, it will have B2K as one of the codes. That means the car was built and shipped to Callaway for the installation of the package and any Callaway-specific options.
Another way to tell is by ordering copies of the build sheet and window sticker from the National Corvette Museum at this page. The two documents are nice to have for for documenting the car as you get the list of options, the final dealer cost and the name of the dealer that it was shipped to.
The VIN pad is on the right front of the block like all SB Chevy motors. As far as the A4 tranny, it's entirely possible that the original 4+3 tranny had been replaced with an auto trans. The 4+3 can be hard to repair and the OD unit as a replacement is pricey by itself. But the RPO sticker will have the "Correct" code for the transmission that went into the car at the Bowling Green Assembly Plant.
There are some 87 Callaway owners on the forum. You can send a PM to forum member TAC to get some information. He has one of the '87 Callaway 'verts.
Ya, this is pretty funny. I'll just start by saying it is NOT a Callaway. This coworker knows nothing of corvettes. This is how it all happened. I asked him to snap some pictures yesterday and bring them in today. So he did, obviously the main picture I wanted to see was under the hood. One quick glance, no twin turbos, a completely stock C4, abeit in gorgeous condition.
So I ask, "why did you think this was a Callaway?" To which he passes me a detailed option list that list every option that was available on a 1987. He points out that the Callaway option had been highlighted in blue (with about 6 or 7 other options) and all the rest were highlighted in red. Of course, his uncle highlighted the options his car had in red, though this guy's mind processes blue = yes, red = no. Though you would think him seeing "coupe" in red and "convertible" in blue would've helped him put two and two together there.
Thanks for all the info, especially 89x2 and c4cruiser.
