As the Gen II 426 Race Hemi turns 50 this year, Mopar guys will be celebrating in a big way! Debuted February 1964 and dominated Daytona 500. The “Hemi” or the hemispherical combustion engine was designed specifically for passenger cars in 1954. The concept behind the Hemi is it produces a vortex in each cylinders through the hemispherical shaped pistons that provides optimal power and performance. The Gen II 426 Hemi, by unspoken rule, is considered a big block because the small block is in the range of 340-360 or known as the SBH (uhm, can you just the use term “small block”, “big block” with the Chevy guys?).
The 426 Hemi is such a vital part of Mopar’s racing heritage, it’s responsible for 26 victories rated at 400 horsepower, cheaper than some equally-powered German and Italian variety and as reliable but with longer life expectancy than any other Japanese “power rice”.
