'1967 Holiday Race' ~ Plymouth GTX 440 vs. Pontiac GTO 400 'Ram Air'

From my days at hanging around at Drag Strips, in the 60s, the majority of street driven Muscle Cars ran in the 14s and 15s. Most of those that ran in the 13s or faster were highly tuned and trailered in, -- OR -- were cheating. -- Just my 2 cents.
