What’s the Fastest Street Vette Ever? The 1988 254.76-MPH Callaway SLEDGEHAMMER!!!
What’s amazing, besides the raw speed and power of the car, is that Callaway never built another one, at least, one that we know of. If they did, the owner kept it a secret because I’ve never seen or heard of another Sledgehammer. If you’re reading this and know of one, please let me know. What a difference nine years made between the ‘79 turbocharged L-48 that the Chevrolet engineering department built and what Callaway made. But to be totally fair, Corvette engineers aren’t in the business of developing mega-horsepower Vette engines, and Callaway isn’t in the business of designing mass production cars. . So, we’ll give the Corvette guys a pass and kudos to Callaway! And to think, this wasn’t a trailered speed machine. Callaway’s team drive it to the track, set the record, and drove it home! AMAZING! here’s the story.
