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
