1964 Dodge/Plymouth Maximum Performance A-864
The biggest news for Mopar in 1964 was the return of the mighty and legendary Hemi 426 engine. Chrysler realized the other manufacturers had caught up with them by using the powerful 413 and 426 Max Wedge engines. The only solution was to bring back the Hemi as the ultimate drag strip weapon. That wasn’t the famous Street Hemi they introduced two years later in 1966 as a regular production option. This was a race-spec Hemi that was not street legal in most states and not available to the public.

They rated the 426 Hemi at 425 HP, but the real output was much more than that. In 1964, Chrysler built just 70 copies, 35 as a Dodge 440 hardtop and 35 as a Plymouth Belvedere hardtop. Most of the cars they produced had an automatic transmission, and some came with four-speed manuals.
