1968 Plymouth Road Runner 426 Hemi
The 1968 Road Runner was Plymouth's back-to-basics B-body performance car: Belvedere-based, deliberately plain, and built around the idea that buyers wanted engine, gearing, tires, and attitude more than luxury trim. The factory Hemi version is the sharp end of that formula. It kept the Road Runner identity and paired it with Chrysler's 426 Street Hemi, dual four-barrel carburetion, 425 advertised horsepower, and the heavy-duty driveline expectations that make real cars paperwork-sensitive today.
The safest public read is narrow. A 1968 Hemi Road Runner should be treated as a factory Road Runner ordered with the 426 Hemi option, not as a generic 383 car with badges or later engine swap. Factory-style references support both four-speed and TorqueFlite availability, F70-14 tire context for 426/440 cars, Road Runner heavy-duty suspension/shock identity, Sure-Grip rear axle options, and Road Runner-specific appearance items such as the beep-beep horn, cartoon emblems, body accent stripes, and optional black hood treatment.
Authentication still belongs to car-level evidence. VIN, fender tag, broadcast sheet, original paperwork, engine and transmission stampings, axle tags, and component dates matter more than captions, paint, or show labels. The gallery uses licensed representative 1968 Road Runner media and reviewed Hemi videos as visual context; it does not claim every photographed car is an original Hemi example.
