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.
Intended to deal with the troubles created by the low-production 426, of which only about 9,000 were built from 1966 to 1972), [4] as well as the different architectures of the higher-volume 383 cu in (6.3 L) and 400 cu in (6.6 L) B and 440 cu in (7.2 L) RB V8s, the ball-stud hemi was to be suitable for high-volume manufacture at low cost while ...

The Polyspheric or Poly engines were V8 engines produced by Chrysler from 1955 to 1958 as lower-cost alternatives to the Hemi engines. [1] These engines were based on the Hemi engines, using the same blocks and crankshaft parts, but completely different cylinder heads, pushrods, exhaust manifolds and pistons.
The 400 cu in (6.6 L) B engine was introduced in 1972 to replace the venerable 383, and were power-rated via the net (installed) method. Chrysler increased the bore size of the 383 to create the 400. Its bore of 4.342-inch (110.3 mm) was the largest used in any production Chrysler V8 at the date of its introduction.
Donovan developed the 417 cu in (6,830 cc) hemi-head V8 to overcome the tendency of 392 cu in (6,420 cc) Chryslers, then used by Top Fuel racers (many of them friends and customers of his), to crack their iron blocks. [1] He copied the 392 cu in (6,420 cc), which he admired, but tried to eliminate its deficiencies. [2]
The Hemi V8 was enlarged to 354 cu in (5.8 L) with 280 brake horsepower (209 kW), and a four-door Southampton hardtop sedan was added to the range. 10,268 were produced. With a wheelbase of 133.0 inches (3,378 mm), longer than the previous year's by 3.0 inches (76 mm), they had the longest wheelbase ever for an Imperial.
