Wasnt the question wrong where it asked who was number 1 then and now? Shouldnt it have been Chevy/Chevy? Toyota may be outselling but they aren't number one yet.
I screwed up on the year smog controls started and the year the hemi engine was introduced.
I think their wrong on the smog question. Isn't a PCV valve smog control? I had one on my 1961 Ford Falcon. And they said smog controls started in 1973.
