Salvaggio Auto Design created this 1970 Plymouth Superbird with modern performance. It starts with a supercharged Hemi V8 built by Gearhead Fabrications making right under 900 horsepower. It features a Demon camshaft, Redeye supercharger, CP pistons, larger injectors, and custom exhaust. A Redeye HP90 eight-speed automatic transmission sends power to a Ford 9-inch rear end. Everything sits on a Detroit Speed custom chassis with a 4-link rear suspension and HRE custom wheels.
