360 vs 383

The fact is the 360 was a smog pig from the factory. 400's and 440's of the smog area were gutless pigs too.
The 5.7 Hemi would walk all over these gutless wonders, Mopar did good with the modern 5.2 and 5.9 very respectable.
Stick a pre 71 383 or 440 magnum with headers in an A-body and get back to me, after you change your undies. lol It ain't your daddies 360 Factory Duster.
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.
