Here's the procedure Pennsylvania requires:


1980 SD1 would not have to do dynamometer test, just idle emissions.

Some counties in PA do not require emissions testing, but the visual
check of emissions equipment tampering is still required.

Also this note: "Vehicles registered as classic or collectible are
exempt from the anti-tampering portion of the safety inspection."
Vehicles not exempt for standard registration.

What constitutes tampering?
"The rule of thumb when it comes to emissions systems is that any
modification that changes the vehicle from a certified configuration to
a non-certified configuration is considered tampering. This applies to
both vehicle owners and repair facilities and is therefore a Federal
offense. Replacing a catalytic converter with a straight pipe is one
traditional example of tampering. Likewise, overriding the OBD system
through the use of high-tech defeat devices, non-certified computer
chips, etc., would also be considered tampering."

Visual Check

        What is a Visual Anti-Tampering Check?
        The Visual Anti-Tampering Check is a visual inspection for the
        presence of emission control components that were installed on
        your vehicle by the manufacturer.
        How is a Visual Anti-Tampering Check performed?
        A certified technician will look for the presence of the
        following emission control devices:
              * Catalytic converter
              * Exhaust gas recirculation (EGR) valve
              * Positive crankcase ventilation (PCV) valve
              * Fuel inlet restrictor
              * Air pump
              * Evaporative control system components such as vapor
                canisters and lines.
        The certified technician will also determine if these devices
        are properly connected and if they are the correct type for the
        vehicle being inspected.
