This 70 Dodge Challenger has style and attitude by the bucket load and is a perfect candidate for a Pro Touring Custom. It isn’t just Mopar fans chasing their dream. Ford guys, GM guys and import collectors alike all regularly have one of these in their collections.

Given this is a Pro Touring Star, let’s begin with the performance bits. The engine is none other than a 426 Gen III Aluminum headed, Stroker Hemi custom built by Muscle Motors Racing, making over 550 HP which will scream its occupants past 150 MPH. The Keisler Engineering 5 Speed Manual Overdrive Transmission kit with a deep throw shifter sticking out of the tunnel will pace through the gears with flair. Putting the rubber to the ground is a new Moser DANA 60 with a huge drilled and slotted 6 piston Wilwood Brake System and Hotchkis rear suspension kit. The Dana 60 is beefed up with 35 spline axles, a Posi, and 3.73 gears. Up front is a complete Reilly Motorsports AlterKtion/power steering/sway bar with a front tubular K member and adjustable coil over shocks. The suspension on this car is state-of-the-art. Try getting an original 69 Roadrunner to handle this good and 100+ mph speeds. The brake system is supplied with 6 piston drilled and slotted Wilwood Brake’s and Hydroboost/ Wilwood Power Master Cylinder Kit. Hold on to the IDIDIT tilt column steering wheel and enjoy the journey.

The spectacular wheels are provided courtesy of Boze Alloys Acute 19” X 10” in the rear wells, and 19” X 8.0” up front. Mickey Thompson Performance Tires will help with the traction and handling. This wheel and tire package is second to none with its combination of performance and style.

Helping the Hemi breathe is a complete TTI Exhaust System, with polished ceramic coated headers, and a 2.5” X pipe exhaust system with Flowmaster Super 44 Mufflers, and SS tips.

When it comes to the fuel, cooling, ignition, and electrical components, only the industry’s top companies were utilized. Fuel for the Hemi is supplied by Quick Fuel and Rock Valley Auto Custom gas tank. The fittings and lines, which plumb the fuel system, are from Summit Racing, JEGS High Performance and Inline Tube. Cooling is performed by a large aluminum radiator with auto electric fans from Mark 7 Radiator. I would not anticipate any overheating troubles with this fire breathing monster. MSD Ignition and new plug wires fire the big Hemi. Wiring upgraded throughout the car, and March Performance Serpentine System with 105 amp alternator,and power steering.

The exterior of this project began as a stock Arizona 1970 Dodge Challenger. After little discussion, the car was entirely stripped and prepped for body. Hours and hours of body work was performed on the panels to get them very straight. The exterior panel gaps are better than factory, and are in perfect alignment. The car was painted “Hemi Orange”/Sherwin Williams Automotive Finishes. A custom Painted R/T stripe on the hood and custom flat black stripes on the side, help break up the orange and add a Nostalgic look. The chrome, trim and brightwork, of course, is straight off of the showroom floor, and shines brilliantly against the orange finish. Check out the custom front gille with skull H4 headlights peeking at you. When building a custom car like this, you can’t forget all of the small details. Something as simple as sandblasting and re-painting a hood latch just adds more perfect fit and finish to a car. Powder coating the suspension pieces adds beauty and durability. You will also notice all of the stainless fasteners throughout the entire car. Stainless bolts were used on the project for long life.
Slip inside and you will quickly see that much of the interior was kept to stock appearance with the help of Thomas Interiors. These Challenger’s were as beautiful from the inside as well as the out, and we didn’t want to mess too much with a proven design. Yards and yards of hush mat was applied to the inner panels to help keep out the sound, heat, and smell. Fully restored gauges were inserted into their respective slots and make a nice show. The wiring on the car was completely re-wired with factory and aftermarket kits. The custom tilt IDIDIT steering column attached to a custom steering wheel feels just right in your hands. The custom upholstered seats are custom wrapped and give a hint of modern style with matching comfort. Carbon Fiber accents were added for a modern touch. A complete restoration of the original dash, heater controls, and gauge cluster was also completed, and all the controls operate flawlessly. The Factory/ Classic Auto Air Heater-A/C system is controlled by the original factory sliders.
