In 1966, Chrysler began offering a
slightly tuned-down version of the 426 HEMI race engine (called the
"street HEMI") as an option in Plymouth Belvederes, Dodge Coronets
and Chargers. The cylinder head configuration with a nearly
centrally located spark plug in a hemispherically shaped combustion
chamber gave the classic HEMI engine its name. |
|
|
|
This unique architecture has an
inherent airflow that translates into big power. The street HEMI
came with dual, four-barrel carburetors mounted on an aluminum
dual-plan intake manifold. The engine's advertised horsepower and
torque were 425 hp and 490 lb.-ft. of torque. |
|
|
|
The street HEMI was optional on all
years of the Dodge Coronet R/T. About 10,000 426 HEMIs were
manufactured for street use in the engine's five-year run. Today,
restored true HEMI cars command very high price tags. |
