Your pic does not show a Thermactor system; e.g., no belt driven air pump, valves, hoses or air injection fittings. What state was the car originally purchased?
Would not matter what state the car was delivered in. By 68 emission requirements were Federal not state like in the 3 prior years. Later in 70 plus there were differences, due to additional - over Federal - requirements for California and some other regions.
Have about two dozen books (Ford and servicing ones) on the subject Have field a fair number of questions from California BAR - Bureau of Auto Repairs in reference to Emission systems on Fords from the 60's a speaker in front of the State Senate related to standards and annual/biannual state inspections in the state
In 68 the requirement for small blocks and 6 cylinders on what transmission was ordered
In allot of locations annual and biannual inspections did not include a check of these systems so removing them was over looked. There is often differences in other parts of the engine and attachments between the Thermactor and non-Thermactor cars. Recall my first MCA show on the east coast and I was instructed to take it "easy" on anything related to Thermactor systems. Did have a discussion with one non- AC 289 68 car owner where I went through a list of things that identified the engine and parts. He eventually admitted that the engine he had in the car came from a Thermactor AC car.
Many parts have been replaced on the engine below but the "big" parts are there. Hard to find a 6 cylinder Thermactor equipped engine and especially out of a car.
Other pictures on a nice unrestored example are available for viewing in the Unrestored Picture Section of the site.
Look for 1968 section then
- 68 T code Dearborn - Unrestored Picture Thread Thermactor
- Early 68 T code San Jose Coupe - Unrestored Picture Thread non-Thermactor original California car just for comparison. There are some additional T code 68 there also
