Supercharged ZR1 power 

Chevrolet Performance acquired a finite number of LS9s for use as crate engines and when they’re gone, they’re gone!

PART NO. 19260165

WhyBuy

638 HP @6500 RPM

WhyBuy

604 LB-FT @3800 RPM

Supercharged ZR1 power 

The engine is a technological marvel. High-rpm-validated lightweight reciprocating parts, including titanium intake valves, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger.
