Enginetech high-performance camshafts are ground to precision specifications using computer-aided design to maximize power output while maintaining street drivability. These performance grinds are designed as direct drop-in replacements requiring no engine modifications. Always install a new timing set and replace all lifters when installing a new camshaft - reusing worn lifters causes rapid lobe wear and premature failure. Verify bore size and journal dimensions match your engine block before ordering.
