Rotisserie Restored, Pro Street! Mopar 446ci V8 (820hp) 8-71 Blower, 727 Auto

1973 Plymouth Road Runner Pro Street

VIN: RM21P3G266996

The body of this Texas car was media blasted, corrosion-protected with steel phosphate, epoxy-sealed, prepped, and then finished in two-stage Sublime Green base and clear polyurethane paint. Rear-wheel tubs and a 12-point roll-cage were added and exterior body mods include narrowed and tucked front and rear bumpers, a laser-cut Chrysler Pentastar grille and scoop inlays, Halogen head and fog lights, shaved handles with keyless entry, integral front and rear spoilers, and rubber items from Year One.

Powering this beast is a professionally built, balanced, and blueprinted engine by Total Engine of Bloomington, Minnesota, based on a new Mopar 426ci block opened to 446 cubic inches with an Enderle-style scoop on dual Holley 750s atop an Indy 8-71 blower. Other highlights include an Indy 440-1 Max Wedge aluminum head and manifold combo, 81 JE forged pistons, Manley rods, an Eagle forged crank, Comp Cams flat-tappet blower cam, ATI damper and gear drive, MSD ignition, Milodon pan, pump, and windage tray. Dual fans and a BeCool radiator keep it all running cool. Coated TTI headers flow spent gases into dual Flowmasters and a fuel cell with Barry Grant pump provides fuel. Dyno-proven at 820 hp and 690 pounds-feet of torque, the wicked blown engine drives power through a 727 Chrysler transmission built by Pro Trans in California, incorporating all aluminum inside, a Turbo-Action 4,800 stall converter, Hurst ratchet shifter, and remote cooler.

A Mopar Collector's Guide Magazine, Dyno Sheet and nicely organized & laminated binder full of receipts and invoices from the build are included in the sale!
