The Hemi-6 is a pushrod O.H.V. (overhead valve engine), with combustion chambers comprising about 35% of the top of the globe. This creates what is known as a low hemispherical shaped chamber. In this way, the "Hemi" moniker was used for the same kind of marketing cachet as Chrysler's 1950s-1970s Hemi V8 engines.
Chrysler developed its first experimental hemi engine for the Republic P-47 Thunderbolt fighter aircraft. The XIV-2220 was an inverted V16 rated at 2,500 hp (1,860 kW). The P-47 was already in production with a Pratt & Whitney radial engine when the XIV-2220 flew successfully in trials in 1945 as a possible upgrade, but the war was winding down and it did not go into production.
The strange car-chase movie 'Vanishing Point' has had an equally strange afterlife, as detailed in this new book about the film and its star, a 1970 Dodge Challenger R/T 440.
The Super 8 Hemi came equipped with a Chrysler 5.7-liter EZB/EZD HEMI OHV V8 engine developing up to 353 hp (263 kW; 358 PS), 395 lb⋅ft (536 N⋅m) torque and has a top speed of 154 mph (248 km/h). It will go from 0-60 in about 5.7 seconds and mated with a four-speed automatic transmission with an Autostick .
Similarly, the Dodge Viper SRT-10 along with the Dodge Ram SRT-10 had an 8.3 L V10. Currently, the quickest SRT production models are the 2023 Dodge Challenger Demon 170 with a quarter-mile time of 8.91 seconds, the 2021 Dodge Challenger SRT Super Stock with a quarter-mile time of 10.5 seconds, [ 4 ] and the 2021 Dodge Charger SRT Hellcat ...
A hemispherical head ("hemi-head") gives an efficient combustion chamber with minimal heat loss to the head, and allows for two large valves.However, a hemi-head usually allows no more than two valves per cylinder due to the difficulty in arranging the valve gear for four valves at diverging angles, and these large valves are necessarily heavier than those in a multi-valve engine of similar ...
Mark Worman wanted to document the restoration of a 1971 Plymouth 'Cuda, painted Hemi Orange, equipped with a 440 6 Barrel V8, a Heavy Duty 4-Speed manual transmission, and a 3.54 ratio Dana 60 rear axle. On July 5, 1980, the car was wrecked after the driver lost control in a 100 mph race with a pickup truck.
