Hemispherical Combustion Chambers Weren't Just a Gimmick: The Chrysler Hemi engine is renowned for its hemispherical combustion chambers, which provide an efficient shape with an excellent surface-to-volume ratio and minimal heat loss.

Three Generations: There have been three generations of Hemi engines: the FirePower series (1951-1958), the legendary 426 Hemi (1964-1971), and the modern Hemis (2003-2024).

FirePower Series: The first-generation Hemi, known as the FirePower series, had displacements ranging from 241 to 392 cubic inches and was produced from 1951 to 1958.

426 Hemi Nickname: The 426 Hemi, produced from 1964 to 1971, earned the nickname "elephant engine" due to its large size and heavy weight.

426 Hemi Power: The 426 Hemi was rated at 425 horsepower and 490 lb-ft of torque, although actual dynamometer testing showed it could produce even more.

Racing Heritage: The 426 Hemi was initially developed for NASCAR racing and made its debut in the Plymouth Belvedere in 1964.

Street Hemi: Chrysler introduced the "Street Hemi" in 1966, making the powerful 426 Hemi available to the general public in various Dodge and Plymouth models.

426 Hemi in Drag Racing: The 426 Hemi dominated NHRA and AHRA drag racing, with its large casting allowing it to be overbored and stroked to displacements unattainable by other engines of the era.

426 Hemi in Iconic Cars: The 426 Hemi was used in some of the most iconic muscle cars, including the 1970 Plymouth Hemi 'Cuda, the Dodge Charger Daytona, and the Plymouth Superbird.

High Compression: The 426 Hemi had a high compression ratio of 10.25:1 in the street version and 12.5:1 in the racing version, requiring high-octane fuel to avoid pre-ignition.

Dual Four-Barrel Carburetors: The 426 Hemi featured dual inline four-barrel Carter AFB carburetors, contributing to its high power output.

Advanced Rocker Arm Geometry: The Hemi engine's complex valve train and large, wide cylinder heads required advanced rocker arm geometry, making it more expensive and challenging to build.

Military Origins: Chrysler's experience with hemispherical combustion chambers began with their development of the XIV-2220 engine for the P-47 Thunderbolt fighter aircraft during World War II.

M47 Patton Tank: Chrysler also used hemispherical combustion chamber technology in the air-cooled AV-1790-5B V12 Hemi engine for the M47 Patton tank.

Modern Hemi Engines: The third-generation Hemi engines, produced from 2003 to 2024, featured advanced technologies and displacements between 5.7 and 6.4 liters, continuing the legacy of high performance.
