The Super Stock Cudas and Darts were NOT street cars:

And the Corvette does 198 MPH - BONE STOCK, has fantastic brakes and handles like it's on rails. It does all of that on 91 octane unleaded and while meeting modern emissions and safety standards and getting 15 city/24 highway MPG per the EPA's latest and most stringent fuel economy standard.
And regardless of what legend and myth would have you believe, the only Super Stock hemi cars that ran 10s back the 60s used FULLY BLUEPRINTED (with chambers cc'd to minimum NHRA tech specs) race hemi engines that were fitted with even hotter than stock cams, aftermarket valvetrain gear, aftermarket oil pans (the factory one was too small) and pickups, custom intakes and carbs, worked suspensions, open long tube headers (aftermarket), etc. The faster examples even ran "experimental" factory heads (e.g. the various "D" series racings heads) that weren't supplied with the original race hemi engines.
The customers/racers also had to dump the entire factory exhaust system, install aftermarket wheels and tires, drag optimized suspensions, etc.
NHRA's Super Stock rules permitted all of that (and more).
Guys like Dick Landy would receive the cars (ALL of which were sold to professional drag racers with factory connections) and modify them as described above - regardless the "out of the box' crap that I've also seen in print.
Here is a mid-10 second NHRA Super Stock Dart - circa 1969. Note the (partial) list of all of the mods and the obviously modified appearance of the car:
