Thanks for that info. As I'm dealing with a 1977 pacer, I guess that I won't have to deal with that.
WHEW!

Every state has different emissions laws. From what I read it seems some states just have a tail pipe standard and if you are under the standard, you pass regardless of what parts the car has - or doesn't. Unfortunately in California every car 1976 and newer there is a visual inspection. EVERY aspect of how the car was originally built has to be in place and functional. The only exception is California Air Resources Board approved aftermarket products.

 So, before you even get to a tail pipe test you can fail. That said the test center is obligated to fully run the test and you pay the full amount (about $60). 1995 to 1975 cars also get a special EVAP test that is roughly an addition $20.  Different counties have different test procedures. OBD2 cars just get the tattle tail scanning of the computer in large population areas. Other areas have to go on the dyno (medium sized cities). Still other areas get stationary idle and 1,500 RPM tests. These test are require every two years or upon the sale of the vehicle. THe SELLER is responsible for providing the buyer with the passing smog certificate. The responsibility can not be agreed upon and transferred to the buyer.  There are a few 'far from general population areas' like north eastern California that only have to smog test on sale of the vehicle.

How people with cars that were festooned with the 70's-80's smog equipment get their cars to pass I'll never know. The parts are likely unobtanium.

Absolutely. 

Sort of like the open combustion chamber cylinder head that the AMC six used from 1968 to 1976. They switched back to the original head that had actual quench area in 1977 as better methods of emission control were developed, and as a result some power and fuel economy was regained. 

The emission control methods of 1966 to 1972 were to basically detune the engine. That is when you saw the retarded ignition timing and stupid cylinder head designs. The advent of ported vacuum EGR in 1973 and catalytic converters in 1975 allowed engines to be tuned back up again. 

Also, the SAE could not have chosen a worse time to switch from gross to net ratings. The public just saw lower numbers and didn't understand why, so they blamed emission control.

That is a very good point of the perception of the general population. Car guys knew the difference in the ratings but the general population likely didn't. It probably would have helped to have both the gross and net HP ratings displayed for a number of years as a transition so the general public could have grasped the difference.

Car guys were the ones who spread the misinformation...and still do... 

There is a lot of nonsense information in the old car community. Even guys with decades of experience are sometimes wrong. You need to do your own research and make up your own mind sometimes.
