Wanna upgrade your rig with some serious horsepower and torque by simply bolting in a ready-to-run high-performance engine? Well, the folks over at Katech Performance have introduced a new supercharged 427ci V-8 that produces up to 750 hp and 700 lb.-ft. of torque. Yep, that oughta do it.
This LS7 block crate engine has gobs of goodies including a Callies forged steel crankshaft and connecting rods; Katech forged aluminum pistons with Diamond-Like Carbon-coated pins; upgraded cam; and stock LS7 titanium intake valve and sodium-filled exhaust valves. Crowning the top of the engine is a Magnuson M122 twin-screw high-helix intercooled supercharger. Optional items include Katech valve covers and TVS-based superchargers. This engine is one of five that make up Katech Performance's arsenal of "Attack" engines. Each engine is completely disassembled, blueprinted and enhanced by the same technicians that produce championship-winning engines for all Katech race programs.
