Chrysler’s “Elephant” Hemi made a heavy comeback in 1964, boasting a whopping 426 cubic inches and enough size to need its own zip code. Known for its robust power, this engine was a hit in NASCAR until it got benched in 1965 for being too exclusive. Revamped for the streets in 1966, the Hemi roared into drag racing fame, proving itself the heavyweight champ. Despite its hefty price tag and appetite for parts, the 426 Hemi remains a legend that left competitors in the dust, or at least eating plenty of it!
