6.4L Hemi-Powered 1971 Plymouth Road Runner

Description

The 1971 Plymouth Road Runner ushered in the second generation with Chrysler’s striking “fuselage” design, featuring sweeping body contours, a loop-style front bumper, and optional “Air Grabber” hood scoops. Built on a 115-inch wheelbase, it blended a more refined appearance with classic muscle car attitude. Under the hood, 1971 marked the final chapter for high-compression big-block engines before emissions regulations and soaring insurance rates reshaped the performance market. Despite its pedigree, sales plunged to 13,664 units — down from over 36,000 in 1970 — signaling the muscle car era’s decline. High-Octane Restorations, Mopar specialists in Savannah, Georgia, preserved that iconic fuselage styling while infusing modern muscle into this ’71 Road Runner. Power now comes from a 2016 SRT 6.4-liter HEMI V8 paired with a performance 727 automatic transmission. Finished in classic Dodge “Lemon Twist” paint with black accents, it sports front eyebrow spoilers, an AAR ’Cuda style rear wing, and a custom trunk stripe. The interior has been refreshed to factory specifications, with the contemporary touch of a retro style radio with Bluetooth. And those custom LED halo headlights are just a hint of what lurks under the hood. This Hemi-powered Road Runner is now offered by a Broad Arrow Specialist with restoration and upgrade receipts, a Bill of Sale, and current registration.
