360 vs 383

Not to sidetrack, but a 3.6 V6 2015 Challenger will run 14.6 and keep up with 80% of the "muscle cars" of the 60's/70's. But again, for the time and era, I think the 383 and 360 did well.

Yes, that's very true, but remember, they have technology on their side, too. They're measured using NET HP, not gross. I'd like to see some gross numbers on the newer engines. There's no denying technology has really made a big difference. I bet the gross numbers would be at least 25% more. Possibly more than that.
