The 426 Hemi engine recently celebrated half a century. In February 1964 at the Daytona 500, Chrysler unleashed a new engine for teams running Dodge and Plymouth cars in NASCAR’s Grand National series. The new 426-cu.in. Hemi V-8 was a game-changer, and the 1964 Daytona 500 saw 426 Hemi-powered cars cross the finish line in first, second and third position, as well as claim two more spots in the top 10.
Keith Black cylinder blocked fuel motor, 1975. The beginning of the evolution from genuine 426 Chrysler Hemi to "Chrysler based" Hemi engines used in virtually all nitro and alcohol dragsters and funny cars since the early seventies.

The Boss 429 is arguably one of the rarest and most valued muscle cars to date. Total production for the 1969 model year was 859 units. The origin of the Boss 429 comes about as a result of NASCAR. Ford was seeking to develop a Hemi engine that could compete with the famed 426 Hemi from Chrysler in NASCAR's Sprint Cup Series. NASCAR's homologation rules required that at least 500 cars be fitted with this motor and sold to the general public.
