In a hemispherical cylinder head, when air enters the combustion chamber through the intake valve, it flows to the exhaust valve instead of being forced through the exhaust valve as pressure is built up in the combustion chamber. While Tom Hoover developed the 426 Hemi engine, cylinder heads can be interchanged between specific engines.
The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower (first generation Hemi) engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi ...
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.
Chrysler Hemi engine: hot rods, older Mopar vehicles, Kit cars, dragsters The 426 Hemi was developed for NASCAR racing. The block is very similar to the 440 Chrysler truck engine, but the heads used a more hemispherical "bowl" shape to allow larger valves. The benefit was the improved high-RPM breathing.
The standard engine was the 440 Magnum, but factory literature described the 426 Hemi as standard. The Charger 500 had the Torqueflite standard and the same equipment standard as the R/T. A total of 392 Charger 500s were made, of which only 67 had the 426 Hemi engine, 27 with a 4-speed, and 40 with an automatic transmission.

Replacement engines are often used to make old cars more reliable for daily driving. Classic car hobbyists may also install reproductions of a rare powerplant in a classic car (this is most often seen in Mopar muscle cars that have the 426 Hemi installed into them). Aftermarket engines are used in many forms of motorsport.
