This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle. Federal guidelines indicate that an engine swap is allowable if one or more of the following conditions apply:

  • If there is a reasonable basis for knowing that emissions are not adversely affected as described in the EPA Tampering Policy dated November 23rd, 2020
  • The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street

Consumers are responsible for complying with laws prohibiting tampering, and for ensuring that modified vehicles are operated in a manner that complies with applicable laws.

The alteration of certified production vehicles to modify, remove, or render inoperable emissions control hardware or software, known as "tampering" is prohibited by the U.S. Clean Air Act and other laws. Tampering with motor vehicles emissions control systems is punishable by substantial monetary penalties.
