February 25, 2009 – Nacogdoches, TX– Did you know you can get 70 more HP than the Z06 427 engine, get a professionally hand built 427 LS3 engine and save thousands? You can with a Mast LS3 427 SS engine! The Mast LS3 427 SS includes a pre-calibrated and dyno tuned fully sequential Mast M-90 drive by wire ECM with a plug and play wiring harness for $13,995 plus shipping! But that’s about the same price as a GMPP Z06 427, isn’t it? Because Mast includes a pre-calibrated and tuned M-90 fuel injection system with plug and play wiring harness, wet sump oiling system, air filter, IAT sensor, a drive by wire foot pedal, starter, harmonic balancer, water pump, all necessary sensors and oil pan (your choice of F-body, Y-body or truck) and you save thousands.

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.
