Chevrolet celebrated the Corvette's 35th anniversary with a special edition, a white coupe with a black top. 2050 of this limited edition were built and sold. Otherwise, the 1988 Chevrolet Corvette remained similar to those of the prior few years, and featured the last 4+3 transmission, which would be replaced with a 6-speed manual in 1989. The base engine was a 5.7-liter, 350-ci V8 rated at 240 horsepower. The Callaway twin turbo option could up this to about 380 horsepower. And lets not forget about the 1988 Chevrolet Callaway Sledgehammer Corvette.Engine Type: Twin-Turbo V8, Displacement: 5733 cc, Horsepower: 880 bhp @ 6250 rpm, Torque: 772 lb-ft. Performance 0-60 mph: 3.9 sec (about the amount of time it takes most of us to just unlock our car door). 0-100 mph: 9.4 sec (thats faster than many cars can get to 60mph). Quarter Mile: 10.6 sec @ 127 mph, Skidpad: .98g , Top Speed: 254.76 mph (those are Nascar speeds my friends). Braking, 60-0 mph: 122 ft, Slalom Speed: 65.6 mph. There is only one of these Calloway Sledgehammer Corvette cars at the moment that I know of. Callaway at the time of building this one said they could/would make another or others for 400,000. US dollars. The top speed of 254.76 MPH was attained by John Lingenfelter as the driver, and apparently was not an official documented recorded speed. Although the production was only limited to one, I am sure that if more people who bought much more expensive vehicles would have weighed the overall package, they may have bought one of these. After all it still is a small block Chevy, okay a 880 H.P. one at that...lol. Lets not forget that this car is 17 years old too. This was not a factory option, but for the money you could add this Callaway package.
