In this way, the "Hemi" moniker was used for the same kind of marketing cachet as Chrysler's 1950s-1970s Hemi V8 engines. The Hemi-6 valves are angled apart (splayed) 18 degrees (included angle) along the crankshaft axis, and the intake valves are as large as 1.96 in (50 mm). The 6 intake and 6 exhaust valves open slightly towards each other ...
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.
Being nearly identical, it too has the distinctive odd-sided hexagonal shape. These engines can be fitted in rear wheel drive vehicles with the right bellhousing and are used in hot rods, kit cars, sand rails and late model engine swaps. All Cadillac Northstar V8s; Oldsmobile Aurora L47 V8; GM 3.5L LX5 "Short Star" V6
This 108 cu in (1,767 cc; 1.8 L) unit is an AMC designed air-cooled V4 engine that was only used in AMC's lightweight aluminium-bodied M422 'Mighty Mite' military vehicle, built from January 1960 to January 1963 as an air transportable (by the helicopters of the time) Jeep for the U.S. Marine Corps.

A total of 1,907 A12 M-code 440 Six Pack 1969 1/2 Dodge Super Bees were produced. This option fell half-way between the standard engine and the Hemi as a US$463 option. The 1969 model year included the base 383 Magnum, 440 Six Pack, and the 426 Hemi. The 440 Magnum (4bbl) was reserved for the Coronet R/T.
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 ...
Came on a blister pack as a "Two Ninety" replacement engine. Basically a replacement 190 engine. An aluminum back plate was used for the "Spook" flying wing combat model kit engine (290-1). 2000 Surestart (Cat#191) Another variation of the modern Babe Bee. These were pretty good because they have a choke tube attached to the grey plastic backplate.
The 1969 model year was also VAM's first self-engineered engine, the 170 hp (127 kW; 172 PS), 9.5:1 compression ratio 252 cu in (4.1 L) I6 engine with a two-barrel Carter WCD carburetor and a new VAM-engineered 266-degree camshaft in both standard and Go Pack versions. This new engine was a major improvement for the Javelin as a performance ...
