11: 1968 Plymouth Barracuda Hemi
Also building on the legendary Hemi name was the Barracuda Hemi. This car tends to get overshadowed by other models in the Plymouth lineup but it was quite the powerhouse. The styling was in line with the rest of the performance lineup around this period (via Autowise).
As far as true enthusiasts are concerned, the Barracuda is the stuff of legend. The car took the nameplate from boring to being the pinnacle of performance. Of course, other well-known Plymouths could break records on the track, but this was the main one.
