Complete engines are offered in a three configurations; a hydraulic roller cam carbureted engine, one with EFI, or a solid roller cam engine with a Dominator style carburetor. They are all conservatively dyno rated at 600 horsepower, and backed by a 2 year/24K mile limited warranty. An optional upgrade to CNC ported heads is good for another 30 horsepower!
