Muscle Car Of The Week Video #63: 1971 Plymouth Road Runner 426 Hemi http://www.musclecaroftheweek.com - This week, we're taking a look at a Hemi powered muscle car featuring a cartoon character in the grill. This 1971 Hemi Road Runner is a very limited production car that still retains a full-power 426 Hemi. It features outstanding details like the functional air grabber hood feeding fresh air to the 425 hp, 426 cube Hemi V-8. Inside, you will find a bench seat, a four-speed handle and little else. The exterior styling is bold with the new-for-1971 styling and the distinctive reflective stripe. It is one of many Hemi powered cars in the Brothers Collection and it is our Muscle Car Of The Week!
