The 5.7 L Hemi is made at Chrysler's Saltillo Engine plant in Ramos Arizpe, Mexico. The Hemi was on the Ward's 10 Best Engines list for 2003 through 2007, and again in 2009. This engine has been used in the following vehicles: 2003–2024 Ram Pickup; 2004–2009, 2011–Present Dodge Durango; 2005–2008 Dodge Magnum R/T; 2005–2023 Chrysler 300C,
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. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi ...
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 ...
The Hemi-6 is a pushrod O.H.V. (overhead valve engine), with combustion chambers comprising about 35% of the top of the globe. This creates what is known as a low hemispherical shaped chamber. In this way, the "Hemi" moniker was used for the same kind of marketing cachet as Chrysler's 1950s-1970s Hemi V8 engines.
4.342 in × 3 + 3 ⁄ 4 in (110.3 mm × 95.3 mm) bore x stroke, 8 cylinders, each having a bore of 4.342 inch and a stroke of 3.75 inch, results in a displacement of 444.21 cubic inches (7,279.34 cc); for the Pontiac OHC 427 Hemi refers to it as a "TOHC" and lists the bore at 4.257 inch—which, with a stroke of 3.75 inch, results in a ...
The Hemi 5.7L engine was dropped (except only Mexico-market Ram 4000), and the Hemi 6.4L becomes the base engine. For 2500 and 3500 pickups with the 6.4L, a ZF 8HP75-LCV 8-speed automatic is mated. The 6.7-liter Cummins turbo-diesel returns in both Standard and High-Output form, but with a new compacted graphite iron (CGI) block.
Some of the changes to facilitate this were using a 1970–93 coolant pump so that older pulleys and brackets could be used, as well as an intake manifold that uses a carburetor instead of electronic fuel injection. With a high lift cam and single plane intake, the crate Magnum 360 cu in (5.9 L) was rated at 380 hp (283 kW) with the Magnum heads.
The police version of the Dodge Charger was made available with a choice of a 3.6-liter Pentastar V6 (292 hp) or 5.7-liter HEMI V8 (370 hp) engine, larger 14.5-inch front brake discs, increased front-caliper swept area from 289 sq.in to 388 sq.in., increased rear-caliper swept area from 291 sq.in. to 296 sq.in., Police-specific Secure Park ...
