67Dart273 you did not say what Idaho has for smog or is it 66 and newer also.

In my part of Idaho (North Idaho--it's a state of the mind) there is no testing. I think only two counties in southern ID require testing, one is Canyon county
Found this:

The following types of vehicles are exempt from emissions testing requirements according to Idaho Code §39-116B as specified in IDAPA 58.01.01.517.05.
- Electric or hybrid vehicles
- Motor vehicles with a model year less than five years old
- Motor vehicles with a model year older than 1981
- Classic automobiles as defined by section 49-406A, Idaho Code
(NOTE BELOW about "Classic")
- Motor vehicles with a maximum vehicle gross weight of less than 1,500 pounds
- Motor vehicles registered as motor homes as defined by Section 49-114, Idaho Code
- Motorized farm equipment
- Vehicles solely engaged in the business of agriculture (defined as "Farm Vehicle" pursuant to Idaho Code 49-123(2)(d))
The Canyon County and City of Kuna vehicle emissions testing program has been developed to operate a Basic I/M Program as defined by 40 CFR 51.352 to regulate emissions from light duty vehicles. For the purposes of this program, light duty vehicles have been defined as vehicles with a GVWR of 14,000 pounds or less.
Vehicles will be tested every two years.
THE FOLLOWING IS TROUBLING!!!!
If you change the engine in your vehicle, you must have the emissions control equipment that was required for the chassis year or engine year,
whichever is newer.
THIS MEANS that late, modified engines in my (smog free) 67 would bring it into the radar, if I lived in a required county/ city.

The trouble with "CLASSIC VEHICLES"

TITLE 49
MOTOR VEHICLES
CHAPTER 4
MOTOR VEHICLE REGISTRATION
49-406A. Idaho classic -- Special license plate program -- Registration and standard license plates. (1) Any motor vehicle or motorcycle which is at least thirty (30) years old that does not qualify as an "Idaho Old Timer" and that is maintained to its original likeness using original-type parts and materials, without major modifications shall be known as an "Idaho Classic." Any motor vehicle which is altered from its original design is not an "Idaho Classic" as herein defined.
(2) Any motor vehicle or motorcycle which qualifies as an "Idaho Classic" shall be used for exhibits, parades, tours, club activities and such occasional use as is necessary for operation and maintenance of the vehicle, and shall not be used for business or commercial purposes or as customary and usual transportation.
=======================================================================================
While there is more to the above code, the important part is, you cannot modify the vehicle, and you can't drive it much. So if you license the car "regular" plates, and you have a newer model or modified engine, NOW you are in the 'smog zone.'
While we currently don't have tests in Kootenai county, a few years ago, there was "some noise" about imementing them because of air drifting over from Spokane. I haven't heard about this lately
On the other hand, WA state has been making noise about ELIMINATING tests!!! Evidently they figure there is a high enough ratio of unmodified newer vehicles, that testing is a losing (a MONEY losing) proposition. They estimated that in a few years there will be no inspections in WA state!!!
