FACTORY FOUNDATION FOR BOOST
As the foundation for the supercharged engine that powered the 2009-13 Corvette ZR1, our LS9 is a long block built for boost—delivered without the supercharger or
front-end accessory drive system, allowing the builder to finish the engine with the power adder of his or her choice. It is rated for 12 lbs. of boost.
The assembly includes a forged rotating assembly (including lightweight titanium connecting rods), rotocast aluminum cylinder heads with titanium intake valves
and stainless hollow exhaust valves, multiple engine sensors and six ignition coils. It also includes a dry-sump oil pan, which requires the builder to add an external oil tank.
Whether you use a supercharger or turbo system, the LS9 long block is the assembled foundation developed for the boost you want to make. It made the C6 ZR1 a legend in its own time—and there’s no telling where its performance potential will take your project!
