Emissions:

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 an 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
