1970 Dodge Challenger - A Plum Crazy Barn Find

By , Photography by

Who: Chad Maskrey
What: 1970 Dodge Challenger
Where: Des Moines, Iowa

Engine: The most popular Street Hemi comes with a 4.25-inch bore and a 3.75-inch stroke, tracing its roots to the '64 race engine version. The '70 Street Hemi version enjoyed the best compression at 10.25:1 and used a hydraulic lifter camshaft for the first time, rated at 284 degrees of duration with 0.490-/0.481-inch lift. The factory rated the power at a conservative 425 hp with 490 lb-ft of torque, and this was still the gross horsepower ratings. That would change to net power in 1972. All Street Hemis since 1966 came with dual four-barrel Carter AFB (aluminum four-barrel) carburetors, and the front carb was different than the rear. Other factory equipment included a dual-point distributor.

Transmission: Hemi Challenger and 'Cuda buyers in 1970 had a choice of the durable but heavy New Process A-833 cast-iron four-speed or the 727 TorqueFlite automatic. This Challenger was fitted with the legendary three-speed automatic, which in the early '70s was perhaps the best automatic trans on the market.

Rearend: Most Hemi E-bodies came with Dana 60 rear axles, and this car was originally equipped with a 4.10:1 rear gear and a Sure Grip limited-slip. Later, the Challenger was converted to an 83⁄4-inch rear with taller gears, but Chad says the new rear's date code is also 1970.

Suspension: The Challenger came with an unequal-length upper and lower control arm front suspension using torsion bars rather than coil springs. A front sway bar was standard with the R/T and optional in the rear. In the rear, the Challenger used Chrysler's excellent asymmetrical leaf spring configuration to control axle wrap-up.

Brakes: Standard brakes for R/T Challengers were 11x3-inch drums in front and 11x2.5-inch in the rear. Can you imagine a Hemi with drum brakes? This Hemi car came with the optional 10.75-inch-diameter rotors with a single-piston, floating caliper that we will guess are barely adequate.

Wheels/Tires: Standard rolling stock for the Hemi Challenger was 15x7-inch steel wheels with E60x15 Goodyear Polyglas GT tires. There was a slotted Rallye wheel available as an option.

Paint/Body: Did you know that the Challenger had a 2-inch-longer wheelbase at 110 inches, compared to its 'Cuda cousin's 108-inch span? This Challenger was originally painted Plum Crazy (paint code FC7), but somewhere along the way, it gained a more pedestrian silver/gray hue. This Challenger also has the standard painted gas cap, as opposed to the optional chrome flip-top cap version.

Interior: The Rallye dash cluster was a popular option that included a 150-mph speedometer, along with a full complement of tach, oil pressure, water temp, and ammeter gauges. One of the previous owners replaced the factory rev counter with a Stewart-Warner mechanical drive tach and a couple of gauges below the dash. This Challenger also has the C16 optional console and the Rim Blow steering wheel.
