Reminds me of when Honda designed and installed CVCC cylinder heads on a Chevy 350, and were able to get those engines to pass the 70s emissions standards without a catalytic converter. Instead the EPA ruled that all cars must have a catalytic converter, even if you could figure out other ways to pass emissions. Must have taken a lot of pressure off of the US automakers at the time when smarter, smaller imports were starting to gain popularity.
