2007 — Z06 LS7 Engine
7.0 liters (427 cu. in.)
505 hp @ 6300 rpm, 470 lb-ft @ 4800 rpm
With a screaming 7000-rpm redline, the LS7 is Chevrolet’s highest-rated naturally aspirated production small-block V-8. It’s a special larger-displacement version of the V-8 engine in regular Corvettes, and is hand-built in Wixom, Michigan. High-performance tricks include titanium connecting rods, a titanium exhaust, and dry-sump oiling. To maximize the engine’s performance potential, the Corvette Z06 itself saves weight with an aluminum space frame and carbon-fiber door panels. Chevrolet says the Corvette Z06 can hit 60 mph in 3.7 seconds and a top speed of 198 mph. The size of the engine (427 cubic inches) matches up to big-block Corvettes from the 1960s, but the LS7 was indeed based on the framework for the small-block V-8.
