Enginetech high-performance camshafts are ground to precision
specifications using the latest computer-aided design concepts to optimize power output
while maintaining street drivability. These performance grinds are designed as direct
replacements that bolt in without engine modifications. Always install a new timing set
and replace all lifters when replacing a camshaft - reusing worn lifters will cause
rapid failure. Use the specified hydraulic flat or roller followers as noted. Verify
part fitment by year, make, model, and engine displacement before ordering.
