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.

Also called the GM small corporate pattern and the S10 pattern. This pattern has a distinctive odd-sided hexagonal shape.

The Vortec 8100 L18 is a big-block V8 engine primarily used as a truck engine. It was a redesigned Chevrolet big-block engine and was introduced with the 2001 full-size pickup trucks. It is an all-iron engine (block and heads) with two valves per cylinder.
The 7.0 L (6,967 cc; 425.2 cu in) big-block was the first tall-deck "big block," produced from 1965 through 1967. It is arguably the best engine Olds made in the muscle car era, although it never made it into a "muscle car". It used a 4.126 in (104.8 mm) bore and 3.975 in (101.0 mm) stroke.
The resulting engine was somewhat improved as to power and efficiency. The 5.9 L V8 engines followed suit in 1989, but also received the overall improved "308" cylinder heads (casting number 4448308) that featured significantly higher flowing exhaust ports and a return to the original 1971 (non-fast burn) combustion chamber.

The first engine called "Hemi" by Chrysler, [ b ] the 426 was nicknamed the "elephant engine" at the time, a reference to its high power, heavy weight, and large physical dimensions. [ 17 ]
The premier SD 421 cylinder head was the late 1962-early 1963 casting #9771980 aka "980", featuring a larger 185 cc (11.3 cu in) intake port volume, flowing 230 cu ft/min (6.5 m 3 /min) at 28 in (711 mm). The 421 HO (High Output) was introduced in 1964 as Pontiac's most powerful engine, replacing the 421SD as Pontiac had to discontinue their ...
