360 vs 383

Sadly enough, the "hottest 360's" from the factory came in a smog era, or in heavy trucks/vans/RC's. I think the 360 4bbl A-body ran 14.6's ??? I'd have to verify. But even a police E58 pulled from a Diplomat could compete with the late sixties/early 70's muscle cars if put in a '70 Duster with dual exhaust and 3.55's. No add-ons needed! Not even headers.
