DESCRIPTION
In the mid-1980s, General Motors sought a weapon to elevate the fourth-generation Corvette into the upper echelons of the global supercar market. Rather than managing the development strictly in-house, Corvette Chief Engineer Dave McLellan authorized a legendary collaboration with Reeves Callaway's engineering firm in Old Lyme, Connecticut. The result was Regular Production Option (RPO) B2K, marking the first and only time in Chevrolet's history that a specialist manufacturer was entrusted with a factory-ordered, factory-warranted powertrain upgrade.
Standard Corvettes were shipped directly from the Bowling Green assembly plant to Callaway Engineering. There, the 5.7-liter V8 engines were disassembled and remanufactured using stouter componentry. Callaway added a forged crankshaft, four-bolt main bearing caps, sturdier connecting rods, and low-compression Cosworth or Mahle pistons. Fed by twin Warner-Ishi or Rotomaster turbochargers and dual intercoolers, output jumped to a monumental 345 horsepower and 465 lb-ft of torquepropelling the Corvette past contemporary supercars from Stuttgart and Maranello for a fraction of their cost.
This particular B2K Twin Turbo is finished in an aggressive, period-correct Black. The 1987 models retained the beautifully clean, iconic wedge lines of the early C4 chassis. The exterior hints at its exceptional performance via subtle, elegant markers: a pair of functional, integrated NACA hood ducts designed to feed the twin intercoolers, a discrete ""Callaway Twin Turbo"" badge on the rear fascia. This particular corvette benefits from lightweight BBS wheels. The paintwork remains in excellent condition throughout.
The cabin is swathed in Tan leather with matching carpets. It features the highly bolstered, factory dual power sport seats and the iconic 1980s digital liquid-crystal instrument cluster. Everything inside remains exceptionally well-preserved and authentic to its era. The interior serves as a time-capsule of late-80s American performance luxury.
Mechanically, this Callaway Corvette has been meticulously maintained and remains in superb operating condition. The twin-turbocharged power plant delivers a visceral surge of boost, channeling its power through the heavy-duty Doug Nash ""4+3"" manual overdrive transmission. This vehicle comes accompanied by an extensive, highly structured history file. It includes the original factory documentation, historical service invoices, and unique Callaway literature confirming its assembly numbers and authenticity. It is ready for immediate enjoyment on the open road or your local cars and coffee.
