1988 254.76mph Corvette For Sale

Record-Breaking ’88 Callaway Corvette ‘Project Sledgehammer’

Record-Breaking ’88 Callaway Corvette ‘Project Sledgehammer’ Is up for Auction.

Reeves Callaway‘s company partnered with General Motors in 1986 to produce a TwinTurbo version of the Corvette. GM assigned the project RPO B2K and Callaway cars were sold by Chevrolet dealers worldwide. 510 cars were hand built by Callaway Cars in Connecticut. It was important for the Corvette to establish top speed bragging rights when car magazines of the day used top speed shoot-outs as a way of awarding the title of Fastest in the Land.

Callaway embarked on Project Sledgehammer to win each of those events every year. Callaway engineers emphasized normal every-day drivability in a car that could attain 250 miles an hour. Most of the contestants were thinly disguised race cars. Not the Callaway Sledgehammer.

To prove it could be done, in October 1988, the Callaway Sledgehammer left on a round trip from Callaway headquarters in Connecticut to the Transportation Research Center’s 7.5-mile oval track in Ohio. Not in a trailer, mind you, but under its own power! At the end of a week-long test and a few development steps, test driver John Lingenfelter set an official speed of 254.76 mph! To put this in perspective, it took nearly twenty years for the Bugatti Veyron to achieve 257 mph in 2010.

If you want the fastest Corvette known, it is now up for auction on Bring a Trailer.

Weekly Special #1

2016 3LZ, Z06, Z07
With only 2,660 miles!

What Mike Likes about this Corvette:
“This 2016 Z06 belonged to the consummate car collector and Corvette aficionado from Anaheim California. He would constantly bug me for a performance vehicle with an automatic transmission, but what he wanted did not exist. It took years but Chevrolet, and Corvette specifically, was finally able to design the ultimate performance vehicle transferring maximum amounts of horsepower through the gearbox of an automatic transmission! We were finally able to order a Z06 with the Z07 package with the automatic transmission, so I immediately set my buddy up with our good friends from MacMulkin Chevrolet to order this ultimate Z06 rocket ship! Now, five years later, he has decided to let his babied, pampered, and garage kept slingshot of a performance vehicle like none other on the streets of America go to another loving home. Barely broken in with ultra-low mileage you can be the recipient, and the second owner, of this amazing vehicle cared for like no other with options that only a very select few have left the factory with.

Are you ready for the ultimate ride of your life?”

The owner of this ’16 Z06 checked a lot of boxes when he ordered it brand new. 3LZ Equipment Group, Competition Sports Seats, Transparent and Painted Roof Panels, Z07 Performance Package, and more.

He also had all of the vents custom painted Arctic White to match the rest of the car for that monochromatic look. It’s a local CA. car and the condition is outstanding throughout, having traveled only 2600 miles since new!

price: $89,900

Weekly Special #2

1969 L71 427/435
frame off restored

What Mike Likes about this Corvette:
“The ’69 Sharks were great cars! The growing pains of ’68 were pretty much all gone by then. But what I liked most was a very rare, one year only option, designated N14. This was the side mounted exhaust system. It consisted of 2 long insulated mufflers surrounded by chrome finned covers and was only available in ’69. To me, this was one of the coolest options ever offered on a Corvette. Add to it the L71, 427/435hp big block (like the car featured here) and you had an almost unbeatable combination of power and style!

And it sounds MEAN!!”

The beautiful and very correct Fathom Green example presented here is one of those that left St. Louis with the N14 exhaust. It’s also equipped with the L71 427/435hp big block, M21 close ratio 4-spd., K66 Transistorized Ignition, tinted glass, power brakes, headlight washers and more.

The car has undergone an extensive, frame off restoration and it is believed that the factory drivetrain is still in place (as evidenced in a report by C3 guru Mark Donnally). The car has received an N.C.R.S. Top Flight Award and factory docs include an N.C.R.S. validated Tank Sticker, Owner’s Kit and keys.
