The car is powered by a 440 Six-Pack V8 that was swapped in during its life, and while the exact mileage on the engine is unknown, it runs strong and has the right performance components: a steel crank, ported\/polished 906 heads with a 3-angle valve job, 10.25:1 compression, and the famous Purple Shaft .509 cam. Fuel delivery comes through the classic triple-carb Six-Pack setup, giving this Roadrunner its unmistakable sound and throttle response.<\/p>\n<p>Backing the engine is the desirable 18-spline Hemi 4-speed transmission, paired with a pistol-grip shifter\u2014one of the most sought-after drivetrain combinations in the Mopar world. Power flows to a Sure-Grip 8.75 rear end equipped with 3.55 gears, offering a great blend of street manners and muscle.<\/p>\n<p>The Plum Crazy paint is an older respray and presents as driver quality, showing normal wear but still attracting plenty of attention. Inside, the white upholstery remains in decent, usable condition. The headliner, however, has tears on both the driver and passenger side rear sections, and those areas are clearly shown in the photo so buyers know exactly what to expect.<\/p>\n<p>The trunk area is solid, and the car overall shows good bones. It retains drum brakes and the original 15\u201d wheels, which help maintain the factory look. The Air Grabber hood is fully functional, the lights and horn work (horn is aftermarket), and the car runs and drives well for an honest big-block Roadrunner<span class=\"s3\">.<\/span><\/p>\n<p>This \u201971 Roadrunner offers the right features\u2014440 Six-Pack, Hemi 4-speed, Air Grabber, Plum Crazy\u2014and presents as a solid, enjoyable driver with room for improvement.
