Ford designed and intended this M-6250-X303 Small Block Drag camshaft for competition use only or off-highway use only. It should not be installed on a vehicle that is driven on public roads and highways. Installation of this part on a vehicle driven on public roads and highways is likely to violate U.S. and Canadian laws and regulations relating to motor vehicle emissions.
