That supercharger is mounted atop an engine that uses the standard Corvette’s aluminum block. To handle the increased power, the LT4 uses forged pistons; strong-er, custom-machined steel connecting rods; and titanium intake valves fitted to cylinder heads that are rotocast of A356T6 aluminum for greater strength and heat resistance. It runs a 10.0:1 compression ratio, relatively high for a supercharged engine, thanks in part to the direct-injection system shared with the Stingray’s V-8. The LT4 also uses the same variable-valve-timing and cylinder-deactivation systems as the Stingray’s LT1.
