ENGINE ASM-GASOLINE 6.2L LS9 (GOODWRENCH)


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!
