1964 Dodge 426 Hemi

At the center of Chrysler’s contribution to American high performance is a storied engine of remarkable archievement: the Hami. The company’s original run of Hami V-8s ended in 1958, with a 390-bhp 392-cid edition. The desing was sound-large, hemispherical combustion chambers are highly efficient, but Hemis were complex, heavy and expensive. Let’s take a closer look to the 1964 Dodge 426 Hemi, one of the faster cars from 1964.

By the early 1960s, stakes were high enought for Chrysles to try again. To win on NASCAR’S super speedways, and dominate at the cutting edge of drag racing, Mopar engineers devoloped a Hemi based on the 413/426 wedge head engines. It still was costly and complicated, but the new mill weighed just 67 pounds more than the wedges. Maximum advertised horsepower for the 426 cid Hemi was 425. Rumor had dyno needles breaking at 600 bhp.

These engines were reserved for the racing,and their impact was inmediate. Debuting at the Daytona 500 in Febrary 1964, they prompty swept the first three places in NASCAR’s premier eventl. Stock car racing Hemis had a single Holley four-barrel atop a dual plane high rise intake manifold and were used with a four speed manual gearbox. Drag-racing versions had a ram-tuned aluminum induction system with Carter AFB dual quads.

Available only in special order intermediate size Dodge and Plymouth models, they ran the four speed or the TorqueFlite automatic, which was in last year with pusbuttons.

Available from the factory were a series of sub-12 second supercars that used aluminum for the hood, front fenders, doors, and some body panels. A lightened front bumper and magnesium front wheels were standard. The car had not radio, no heater, no back seat or carpet, no sound deadening material. Fatherweight Dodge van bucket seats were used, the side windows were plastic, and the battery rode in the trunk.

Street version of the Hemi engine wouldn’t be available for a couple of years. But King Kong had arrived

Extra information

Arriving in 1964, the 426 Hemi inmediately propelled Dodge and Plymouth into NASCAR’s winner’s cicle and into a drag-racing dominance. The most popular Hemi Dodge was midsize 330/440 Polara. This is a 330 with the maximum Performance Packege. It’s a factory built, Super Stock class quarter miler with aluminum body panels and lightweight interior components. The race Hemi powertrain uses a TorqueFlite with dash-mounted pushbuttons. It wouldn’t have been pleasant, but this car was street legal.
