in addition, I’d bet the torque of the old bore and stroke engines would indeed smash todays high RPM based transmissions...
The '70 440 six-pack had 480 lb-ft of torque while the Hellcat has 650 lb-ft.
The '70 440 six-pack took 6 seconds to get to 60 mph and the Hellcat takes 3.6.
The '70 440 six-pack was 13.6 through the quarter mile while the Hellcat is 11.9.
