You forgot the best non-Mopar compact of all; the 1966 L-79 350 horsepower 327 Chevy II.
If it had decent bite (slicks and slapper bars) A-body 340's couldn't touch it.
It was a one-year only option though, so they weren't around as new cars in 1967. And, that engine wasn't available in a Chevy II in 1965.
The Chevelles with that motor ran ok, but were a little heavier.
It had a tiny, 565cfm Holley on it, or it could have been a giant killer.
In almost every other way, though, a Valiant or a Dart was a MUCH better car!!! From brakes to suspension, the Mopars made the competition look very inferior. And it stayed that way thru the '70s.
