You can't. Emission engines, particularly V-8s, in the late 70s used retarded ignition timing, to increase burning time. This was before compression was lowered, egr perfected etc etc. Pre electronic anything. Many engines had a vacuum retard diaphragm on the dist, so in high vacuum conditions, ie traffic jams, engine idling, timing would be pulled back. Yes, power was way down, fuel mileage in the tank, and very difficult for a tech to make run well. Every engine was a bit different, with the large bore V8s being the dirtiest. Flame front would go out and border gas (the .008" or so mixture against the cylinder wall being coolest and the cause of most hydrocarbon emissions) would not burn. Hemis went away quickly because of their lack of turbulence in the incoming mixture that would not mix well. Interesting discussion, almost need a white board in a discussion group..........
