360 magnum vs 5.7 hemi

Gotta disagree with you, dgc333. Shortly after purchasing my old '69 340 Swinger used in November 1969, it ran 14.28 @ 98+ mph at OCIR. This with just a tuned stock motor, Goodyear Polyglas GT tires (hard), no headers, no SureGrip, and 3.23 gears. And I still have the trophy to prove it.
That's hardly 'could hardly break into the 14's'.
I'm currently building my "new" '69 Dart with a 380hp 360 crate motor with a few additional goodies and looking for much better performance with a well-balanced overall package.

Well you had a very good running Swinger because the 340 cars typically were high 14 low 15 cars. Even the 383 Road Runners and such were only into the high 14's. And you hit the nail on the head with the tires. The tires of the day weren't at all good for straight line traction.

The other thing to keep in mind is a 340 rated at 275 which was arguably under rated and was more like 300 if measured the same way the measure HP today would be down in the 230 HP range just like a 5.2l magnum motor.
