LS Stage 3 Engine - 1,500 HP To 2,300 HP
LS Stage 3 Engine - 1,500 HP To 2,300 HP
This engine package is incredibly configurable.
Stage 3 LS Engine Package. This package is designed for that 1,500+hp in a cast-block/cast cylinder heads class. These are designed and built for either dedicated drag-race only, or 'drag-and-drive style' events. They are built with strength and reliability in mind based on our years of proven performance.
These long-block engines can be designed as a turbocharged or supercharged engine package. We have a TON of options on front engine accessory drives, power-adder combinations, turbo or supercharger selections! We can add a HOLLEY or FUELTECH EFI system, ignition system, and all the fuel system components as well. Wrap it up with our engine dyno-calibration on your choice of fuels, and you end up with a tested, proven engine combination for your ride!
