The Slant Six, Semi-Hemi and PowerTech are Chrysler's most reliable engines

Chrysler 's first Chrysler -branded car debuted a century ago in the form of the 1924 Chrysler Six , also known as the B70 .

The Slant Six got its unusual name from the angle at which it was mounted in the engine bay.

Efficient and easy to work on, it gave Chrysler a potent response to imports, which had grown in popularity through the 1950s .

For drivers who wanted V8 power without stopping at the gas pump every few days , the 4.7-liter PowerTech V8 supplied the answer.

Fewer than 10,000 426 Street Hemis were ever sold to the public, and as such it's one of the most collectible engines of all time.

The 440 RB (Raised Block) was a mainstay throughout Chrysler 's brands from 1966 to 1978 .

Unlike Chrysler 's Hemi engines with their famous hemispherical combustion chambers, the 440RB had wedge-shaped chambers, giving it the additional nickname of wedge motor.

Chrysler revived the fabled Hemi name in 2003 Dodge Ram pickups.

The current generation of Hemi has its namesake hemispherical combustion chambers slightly flattened at the top, causing purists to argue that it's not a real Hemi .

The 5.7-liter has a cast-iron block while featuring aluminum pistons.
