Each Mast LSX 454 SS crate engine is hand built, blueprinted and features only the finest quality, name brand components from Callies, Mahle, Melling, ARP, Manley, and Ferrea.   The Mast LSX iron block 454 cubic inch engine boasts features like a wet sump oiling system, GM LS7 bare casting heads with custom CNC ports with multi-angle valve job and matched GM LS7 short runner intake, 90MM drive by wire throttle body, and a bulletproof forged bottom end that can also handle the rigors of daily street use.  A purpose designed cam specs out at .666 valve lift on both intake and exhaust lobes for broad power curve.  The unique lopey idle will have you grinning from ear to ear while commanding the utmost respect from all who hear it.

Countless hours of grueling yet highly sophisticated dyno testing on an in-house SuperFlow NSCR SF-902 engine dyno produce maximum horsepower and extreme durability.  Each engine is precision calibrated using Mast’s exclusive M-90 fully sequential ECM with integrated wide band O2 and wide band knock sensor capability.  Initial knock testing and validation uses real-time in cylinder pressure measurement for maximum power under any condition with ZERO engine knock.  This allows safe operation of the engine at peak power levels using any given premium 91 to 93 octane fuel. Once the engine dyno testing is completed, Mast then installs the engine in its actual application to perform transient testing and finalize the calibration.
