  Chrysler Hemi engine - Biocrawler
Chrysler abandoned the hemispherical concept in 1959 in favor of the wedge-head Chrysler B engine.
This famous engine was sized for NASCAR (which mandated engines under 428 in³/7.0 L) with an oversquare 4.25 in (107.9 mm) bore and 3.75 in (95.2 mm) stroke like the Chrysler RB engine big-block.
Chrysler reacted by putting the 5.7 liter Hemi in the 2003 Dodge Ram 1500, 2005 Chrysler 300C and Dodge Magnum, and the 2005 Jeep Grand Cherokee.

 Hemi engine - Biocrawler
Hemi (from "hemisphere") is a design of internal-combustion engines in which the cylinder head's combustion chamber is of hemispherical form.
Chrysler has used the word "Hemi" extensively in its advertising, to the extent that the word is indelibly associated with Chrysler in North America.
Chrysler's first experience with the Hemi design was during World War 2, in which it developed an experimental 2500 hp (1864 kW) V16 engine for the P-47 Thunderbolt.

 Chrysler Hemi engine - Crankshaft Coalition Wiki
Chrysler's 426 Hemi design proved so efficient that, for the past 50 years, nearly all major top fuel and funny car drag racing teams have used derivatives of it.
Hemi engines were being used experimentally in motorcar events, including the Grand Prix, and hemi or hemi-like engine designs were sporadically available in high-end sports cars of the time.
Chrysler had begun work on the engine around 1940, and presented their idea to the United States Army Air Corps, a World War II era predecessor to the modern-day US Air Force.

 Mopar hemi engine
With a lot of trial and error, eventually the highly skilled engineers did resolve the issue, with a change in the tappet material and the method in which the face of the tappet was formed, to reduce the valve unit load; they also added a graphite coating and specified an additive for the engine oil.
Chrysler designed the pistons to be able to "slip" between the crankshaft counterweights at the bottom of the stroke, achieving a much smoother running engine, with less friction and slower wear characteristics.
The 315 Hemi was bored to 3.69 inches with a 3.80 stroke that came to 325 cubic inches.

The 331 and the 354 engines are visually the same in appearance than a 392 engine, so the look of the LARGE HEADS in a street rod or street machine, muscle car will make the Hemi engine seem monstrous in your vehicle.
The distinguishing features are that the inward edge of the area where the water cross over pipe connects is nearly an inch away from the edge of the intake mounting surface, and there are two bosses cast into the ends of the head that were sometimes drilled and tapped for mounting an air condtioning compressor.
The 1955 year 331 engine is similar to the 354 hemi engine as it has water oulets in the front of the heads.

Although Chrysler didn't publicize it heavily, its Hemi was the first engine to produce one horsepower per cubic inch," said Tony Thacker, executive director of the Wally Parks NHRA Motorsports Museum.
So the existing engine — the biggest displacement at that time was 413 cubic inch — was opened up to 426, the block was modified and the new cylinder heads were the Hemi design.
That concept is in the new Hemi engine, the double spark plug per cylinder, the double rocker shafts with the plugs in between them — that's all there.

Predictably, the 1950 Chryslers were repeats of the all-new postwar '49 models save the usual trim shuffles and a broader chrome eggcrate smile.
But the Hemi was complex and costly to build, requiring twice as many rocker shafts, pushrods, and rockers; heads were heavy, too.
Chryslers also did well as NASCAR stockers, but were eclipsed by Hudson's "fabulous" Hornets in 1952-54.

A Chrysler Hemi engine – they spell it big as HEMI – is one of three internal combustion engine families from the company that uses a hemispherical combustion chamber.
The 426 Hemi was nicknamed the 'elephant engine' at the time, a reference to its far from compact dimensions and extraordinary power.
The fierce competition in the Hemi hey days in the United States led to an escalation in power that peaked in 1970, with some models offering as much as 450hp, and the muscle cars' performance became a liability during this period.

 What is a HEMI engine?
Chrysler's marketing campaign has helped to revive the awe of the Hemi engine and has helped to associate the term Hemi with big, powerful engines.
The Hemi engine was introduced by Chrysler in 1951 in a new line of V8 engines called the "Hemi." The name Hemi came from the shape of the cylinder heads, which had a hemispherical design to the cylinder head's combustion chamber.
The term, "Hemi engine", is a trademark of Chrysler Corporation, although the concept is used by many manufacturers.

 Chrysler HEMI(r) Engine Facts
Hemispherical combustion chambers were commonly used in racing engines built up to the mid-1960s, when the success of the Ford-Cosworth DFV Formula One engine led to a resurgence of four-valve-per-cylinder designs with narrow valve angles incompatible with hemispherical combustion chambers.
As in previous Hemis, intake and exhaust valves for each bank of cylinders are at an angle in the head and have their own rockers.
Chrysler estimates at ten to twenty percent increase in fuel economy, and indeed, I found the 300C to be most efficient for a car of its size and power.

 Hemi's Back For DC's Heavies - Daimler-Chrysler Hemi engine to be relaunched on Dodge Ram pickup trucks - Brief Article ...   (Site not responding. Last check: )
The claim to fame for the all-new '03 Hemi Magnum V-8 - to be launched this fall in DC's all-new Dodge Ram heavy-duty pickups - is its unique hemispherically shaped combustion chambers.
Although the original Chrysler Corp. used engines with hemi heads prominently in NASCAR racing, the Hemi that enthusiasts came to revere didn't make it into street cars until 1966, in Chrysler's intermediate-body models; the 429 Hemi engines were gone by 1971.
One problem that cropped up after the decision to adopt the twin-spark design for the Hemi: The basic architecture of the Hemi head meant that the two spark plugs had to be situated slightly offset from one another, which adds a step in the machining of the head.

 Milestones In Chrysler's HEMI History
- Chrysler 300C and Dodge Magnum R/T are the first modern, production North American vehicles to feature cylinder deactivation – the Chrysler Group Multi-Displacement System (MDS) turns off four cylinders in the 5.7-liter HEMI engine when V-8 power is not needed for up to a 20-percent fuel savings.
Its 69.8 horsepower-per-liter rating exceeds even that of the legendary 1966 “Street HEMI.” Torque is rated at 425 hp at 6,000 rpm 420 lb.-ft. at 4,800 rpm.
- Engine breathing in the 6.1-liter was increased with new high-flow cylinder heads, a specially designed intake manifold and exhaust "headers" with individual tubes encased in a stainless-steel shell.
