1997 — All-aluminum LS1 engine
5.7 liters (347 cu. in.)
345 hp @ 5600 rpm, 350 lb-ft @ 4400 rpm
Chevrolet’s LS1 V-8 engine was so impressive that it earned Automobile Magazine‘s Technology of the Year award in 1998. A long list of innovations includes all-aluminum construction and Chevrolet’s first production drive-by-wire throttle and first composite intake manifold. By virtue of using aluminum, the new LS1 was nearly 90 pounds lighter than previous Corvette V-8 engines. After its debut in the Corvette, the LS1 was added to the 1998 Chevrolet Camaro Z28 (producing 305 hp) and the Camaro SS (with 320 hp). By 2001, some minor tweaks added five horsepower to all three models — 350 hp in the Corvette, 310 hp in the Camaro Z28, and 325 hp in the Camaro SS.
