We are proud to be the World’s leading source and the engine re-builder’s first choice for Reverse & Standard Rotation Roller cams for the GM 7.4L / 454ci engine.  Our Flat Tappet Replacement Kit is created to most easily and economically replace decades old flat tappet cam designs while providing noticeable gains in performance and efficiency.  They are intended for Mercruiser, Crusader, Volvo, OMC, and other brands based on the GM 7.4L / 454ci engine, generally found in midsize performance and heavy cruising boats as well as specialized industrial applications.

Our cams are manufactured from a solid billet core using the latest in precision CNC grind technology.  This provides the ultimate in consistent adherence to the designed specifications and duplication.

Allows for using modern day oils without concern of adequate zinc ingredient.

Profiles are designed to optimize a balance of HP, broad mid-range torque, efficiency, idle quality, and longevity, while maintaining OEM fuel systems and octane recommendations.  Plus, the added time and cost savings of no break-in period and no readjusting of valves after break-in.  They also maintain most original part specs while upgrading only the necessary roller cam related parts, and those parts normally recommended in a standard re-build.  All our parts are 100%  Made in the USA.
