Vehicle Description

1973 Plymouth Road Runner Pro Street

VIN: RM21P3G266996

Check out this incredible Pro Street 1973 Plymouth Road Runner! This Road Runner has undergone an extensive Rotisserie Build and lots of custom and high-performance components were added during the process! The body of this Texas car was media blasted, corrosion-protected with steel phosphate, epoxy-sealed, prepped, and then finished in a two-stage Sublime Green Exterior Paint. Rear-Wheel Tubs and a 12-Point Roll-Cage were added and exterior body modifications include Narrowed and Tucked Front and Rear Bumpers, a Laser-Cut Grille and Scoop Inlays, Cutout Hood with Hood Pins, Shaved Handles with Keyless-Entry, Integral Front and Rear Spoilers, Customized Boyd Coddington Wheels, LED Taillights, along with Halogen Headlights and Fog Lights. Inside, this Road Runner is sporting a Custom Black and Gray Interior with Black Carpeting, Front Bucket Seating with Lap Belts, Custom Front and Rear Paneling, AutoMeter Dashboard Gauges, Customized Center Console with a B&M Shifter, Power Windows, and a Custom Upholstered Trunk with a Signed Closeout Panel that hides the Fuel Cell and Dual Batteries. Given its great presence and looks, this Road Runner was selected as a Feature car at the Mopars at the Mansion show, held at the storied Playboy Mansion, and it was a cover subject and centerfold feature car in Mopar Collector's Guide magazine!

Powering this beast is a professionally built, balanced, and blueprinted Supercharged 446ci V8 Engine that was built by Total Engine of Bloomington, Minnesota. This powerplant is based on a new Mopar 426ci block, opened to 446 cubic inches with an Enderle-Style Scoop on Dual Holley 950 CFM Carburetors atop an Indy 8-71 Blower! Other performance highlights include an Indy 440-1 Max Wedge Aluminum Head and Manifold Combo, JE Forged Pistons, Manley Rods, an Eagle Forged Crank, Comp Cams Flat-Tappet Blower Cam, ATI Damper and Gear Drive, Milodon Oil Pan, Windage Tray, Ceramic Coated TTI Exhaust Headers, and an MSD Ignition System. The cooling system has been upgraded with an Electric Water Pump, Dual Electric Cooling Fans, and a BeCool Aluminum Radiator. The incredible engine drives power through a A727 Torqueflite 3-Speed Automatic Transmission that was built by Pro Trans in California, incorporating All-Aluminum Internals, a Turbo-Action Hughes HD 3,000 Stall Converter, Manual Valve Body, and a Remote Cooler. Afterwards, a Mark Williams Narrowed 8 3/4'' Rear End (489 Case) with Chromoly Drive and Axle Shafts, Richmond 3.91:1 Gears, and Sure-Grip in a Reinforced Housing sends power to the massive rear tires. Driving this Road Runner is nothing short of a thrill and stopping power is provided by 4-Wheel Disc Brakes with 4-Piston Calipers and Slotted Rotors! Underpinnings include Body Color Floorboards, Frame Ties, Reinforced Torque Boxes, Front and Rear Driveshaft Loops, Torsion Bar Front Suspension, Leaf Spring Rear Suspension, Rear Traction Bars, and a 3'' Dual Exhaust System with Electric Cutouts and Flowmaster Mufflers!
