Hypothetical build questions…

Yup, Nixon passed it and Carter enforced it by threatening to take away some **** I can’t remember. I lived through it. I know exactly how it happened
Hwy funding among other funding areas. New York was under the same gun again years later. The first Gov. Cuomo decided to adapt California emission standards but he was met with resistance in a big way, he backed down. Until the President threatened to withhold A LOT of money for our Hwy. and other things in the hundreds of millions. He flipped back to the Cali standards. Everyone was pissed at the Gov. a bit but really really pissed at the President.

What sucked for us car guys was a visual inspection for the cars cats. Also, the cars had to be run on rollers to simulate driving down the road. The rollers would detect weight, tire speed and levels of tail pipe pollutants @ the laws 55 mph speeds. To add insult to injury for the car owner, a live camera feed was installed to make sure the computer inputs were for the car being testers and NO shenanigans were taking place.

So, at the time, I was putting together my first ‘79 Magnum and used twin high flow cats off the exhaust manifolds. Thankfully it wasn’t a big deal for the daily driver where power was wallet limited to basic bolt on parts. Not even a cam for the ‘79-360-2bbl engine.

It scooted along well enough and got 20 mpg’s. Work was 25 miles one way, so it was good. She passed emissions as a later F.I. car could. Very clean burning.
