The '''Chrysler B and RB engines''' are a series of [[V8 engine#American|big-block V8]] [[gasoline engine]]s introduced in 1958 to replace the [[Chrysler Hemi engine#First_Generation: FirePower|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 [[Chrysler Hemi engine#426: The Elephant|426 Hemi]] big block engines that are typically referred to as "Hemi" or "426 Hemi" due to their hemispherical shaped combustion chambers. The corporation had been seeking a smaller and lighter replacement for its FirePower engines, in part because new styling dictates meant moving the engine forward in the chassis which negatively affected weight distribution.<ref name=RnM59>((cite journal | last1 = Rarey | first1 = R.S. | last2 = Moeller | first2 = E.G. | title = Chrysler Corporation's New V-8 Engine | journal = SAE Transactions | volume = 69 | date = 1959 | page = 95 ))</ref>

==Design==
Design features of the B and RB engines include 17 capscrews per [[cylinder head]], a [[cylinder block]] that extends ((convert|3|in|mm|1|abbr=on)) below the [[crankshaft]] centerline, an [[intake manifold]] not exposed to [[crankcase]] oil on the underside, stamped-steel shaft-mounted [[rocker arm]]s (race versions used [[forged steel]] rockers), and a front-mounted external [[Oil pump (internal combustion engine)|oil pump]] driven by the camshaft. In order to provide a lower hood and center of gravity, the engine to be mounted lower than before. Apart from changing the engine dimensions and engine mount position, this also entailed reconsidering the distributor drive and oil pump locations. The oil pump could not be allowed to extend below the crank throw to avoid interfering with the steering linkage. The engineers moved the distributor to the front of the engine, at a 45-degree angle, which cleared the heater while allowing the oil pump to be located in front of the block - above the bottom of the crank's throw, clearing the steering linkage.<ref name=RnM59/>

The 'B' series wedge engine was introduced in 1958 with ((convert|350|cuin|L|1|abbr=on)) and ((convert|361|cuin|L|1|abbr=on)) versions. The 361 would continue in production until the end of the series, albeit only for truck installation. The RB ("raised B") arrived one year after the launch of the B series engines, in ((convert|383|cuin|L|1|abbr=on)) and ((convert|413|cuin|L|1|abbr=on)) displacements. Unlike the previous B-engines, which had a ((convert|3+3/8|inch|mm|1|adj=on)) [[Stroke (engines)|stroke]], the RB engines had a ((convert|3+3/4|inch|mm|1|adj=on)) stroke.

For 1960, a "ram induction" system increased the 413's [[torque]] up to ((cvt|495|lbft|Nm|0)) on the Chrysler 300F versions.

The last 'B-RB' wedge-headed engine was produced in August 1978, ending the era of Chrysler "big-block" engines.

==B engines==
All Low Block B-series engines have a ((convert|3+3/8|inch|mm|1|abbr=on)) stroke, a ((convert|9.98|inch|mm|abbr=on)) deck height and ((convert|6.358|inch|mm|abbr=on)) [[connecting rod]]s, resulting in a 1.88:1 rod ratio.

===350===
The ((convert|349.978|cuin|cc|0|adj=ri0|abbr=on)) B engine was, along with the 361, the first production B engine, first available in 1958. It had a [[Bore (engine)|bore]] of ((convert|4+1/16|in|mm in|sigfig=3|abbr=on)). The 350 is classified as a big-block engine. All parts except for the [[piston]]s are fully compatible with the 361.

Vehicles using the B 350:

* 1958 [[DeSoto Firedome|DeSoto Firesweep]]
* 1958 [[Dodge Coronet#Fourth generation (1957–1959)|Dodge Coronet]]
* 1958 [[Plymouth Fury]]

===361===
The 361 cu in B engine also introduced in 1958 was essentially the same as the 350 except with a larger ((convert|4+1/8|in|mm in|sigfig=3|abbr=on)) bore, for an actual displacement of ((convert|360.83|cuin|cc|0|abbr=on)). In 1962, the [[Dodge Polara]] 500 came standard with a ((convert|305|bhp|kW|0|abbr=on)) version of the 361 that had a four-barrel [[carburetor]], dual-point distributor, and dual exhausts. [[Plymouth automobile|Plymouth]] called their versions of the early B engine the ''Commando'', variants of which included the ''Golden Commando'' and ''Sonoramic Commando''. It produced ((convert|305|bhp|kW|0|abbr=on)). [[DeSoto (automobile)|DeSoto]]'s B engine was named ''Turboflash'' and produced ((convert|295|bhp|kW|0|abbr=on)). The [[Dodge]] standard version was a 2-barrel with ((convert|295|bhp|kW|0|abbr=on)) called the ''Super Red Ram'' with an optional variant that was called the ''D500'' and produced ((convert|320|bhp|kW|0|abbr=on)).

The 361 would last until the end of the series, albeit for trucks only. In its early years, the 305-horsepower 361 was optional on many vehicles, and standard on, among others, the Dodge 880. The 361 had a fuel-injected version in 1958 only.<ref>((cite web|url= http://www.allpar.com/mopar/b-engines.html |title=The B Engines: 350, 361, 383, and 400 |work=Allpar.com | editor-first = David | editor-last = Zatz | archive-url = https://web.archive.org/web/20161228223038/http://www.allpar.com/mopar/b-engines.html | archive-date= 2016-12-28 ))</ref> Very few of the fuel-injected B engines were made and only a handful remain, since most were brought back to the dealer to be fitted with carburetors.

===383===
[[File:Chrysler 383 low-block engine, 1964 or 65.jpg|thumb|1964 or 1965 Chrysler 383 B engine]]
The 383 cu in B engine—not to be confused with the RB version—was essentially a larger bore version of the 350 and 361, using a ((convert|4.25|in|mm|1|abbr=on)) bore for a ((convert|383.03|cuin|cc|0|abbr=on)) displacement. This venerable engine was introduced in 1959. Dodge's version, the ''D500'', had a cross-ram induction manifold and dual four-barrel [[carburetor]]s as options. In some Dodge applications, this engine was labeled as the ''Magnum'', while the Plymouth version was called the ''Golden Commando''. Both came with a dual point distributor in high-performance versions.

The 383 became the standard model Mopar performance engine for the next decade. The big bore allowed for larger, ((convert|2.08|inch|mm|abbr=on)), intake valves, and the relatively short stroke helped it to be a free-revving and free-breathing engine.

Producing a maximum of ((convert|330|hp|kW PS|0|abbr=on)) ([[Horsepower#SAE gross power|gross]]) and ((convert|460|lbft|Nm|0|abbr=on)) of torque for the 1960 model year, the 383 beat the 392 Hemi that had reached ((convert|435|lbft|Nm|0|abbr=on)). The 1960 383 engines featured the same basic ram induction system as the Chrysler 300F's 413 RB engines (named ''Sonoramic Commando'' when sold in Plymouth form). The later 383 Magnum (starting in 1968) used the 440 Magnum heads, camshaft, and exhaust manifolds. This engine was advertised at ((convert|335|hp|kW PS|0|abbr=on)).

===400===
The ((convert|400|cuin|L|1|abbr=on)) 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 ((convert|4.342|in|mm|adj=on)) was the largest used in any production Chrysler V8 at the date of its introduction. All parts except for the pistons were interchangeable between the 383 and 400.

Crankshafts were made of cast iron. Three versions of this engine were available: a two-barrel/single-exhaust version producing ((convert|170|hp|kW PS|0|abbr=on)) at 4,400 rpm and ((convert|305|lbft|Nm|0|abbr=on)) of torque at 2,400 rpm, a four-barrel/single-exhaust version producing ((convert|205|hp|kW PS|0|abbr=on)) at 4,400 rpm, and a high-performance four-barrel/dual-exhaust version rated at ((convert|260|hp|kW PS|0|abbr=on)) at 4,800 rpm and ((convert|410|lbft|Nm|0|abbr=on)) of torque at 3,200 rpm. All three versions used the same 8.2:1 compression ratio. The 400 was used in car, truck, and motorhome chassis. Horsepower and torque ratings gradually declined through the years because of the addition of more federally mandated emissions controls, until all Chrysler passenger vehicle big-block production ceased in 1978. For its last year of production, it only produced ((convert|190|hp|kW|0|abbr=on)) (although a heavy-duty version was also available).<ref>((cite book|title=Standard Catalog of Chrysler, 1924-1990 |first=John |last=Lee |publisher=Krause Publications |pages=192, 313 |year=1990 |isbn=0-87341-142-0 ))</ref>

Due to its large factory bore size, short (compared to RB engines) deck height, and bottom end strength that is greater than any other production B or RB engine due to extra material added around the main bearing caps,<ref>((cite web|url= http://www.440source.com/blockinfo.htm |title=Everything you've ever wanted to know about B/RB blocks and more... |work=440Source.com |access-date=January 4, 2016))</ref> 400 B engine blocks have become a popular choice for high-performance engine build-ups.

==RB engines==
The ''RB'' engines, produced from 1959 to 1979, are raised-block (taller) versions of the B engines. All RB engines have a ((convert|3+3/4|in|mm|1|abbr=on)) stroke, with the [[Bore (engines)|bore]] being the defining factor in engine size. All RB wedge engines share a deck height of ((convert|10.725|in|mm|abbr=on)), and were fitted with ((convert|6.768|in|mm|abbr=on)) long connecting rods, resulting in a 1.80:1 rod ratio. Bore center distance is ((convert|4.8|in|mm|abbr=on)). All RBs are [[oversquare]].

===((anchor|RB383)) 383===
[[File:1959 Chrysler B-series 383ci V8 engine in a Windsor.jpg|thumb|RB 383 "Golden Lion" engine in a 1959 Windsor]]
Not to be confused with the 383 ''B'' engine, the 383 ''RB'' had a ((convert|4+1/32|in|mm in|sigfig=4|abbr=on)) bore combined with the long stroke of ((convert|3+3/4|in|mm|1|adj=on)), for a displacement of ((convert|382.905|cuin|cc|0|adj=ri1|abbr=on)). It was only available in 1959 and 1960 on the U.S.-built [[Chrysler Windsor]]s and [[Chrysler Saratoga#1959|Saratogas]]; one of Trenton Engine's lines had been converted to the new RB engine (to make the 413), and demand for the 383 B engine was too high for the remaining line. The solution was to create a 383 RB to fill the gap until the plant figured out how to quickly switch from one block to the other.

===413===
The ((convert|413|cuin|L|1|abbr=on)) RB was used from 1959 to 1965 in cars. It was also used in medium and heavy trucks including truck-tractors such as the [[Dodge LCF series|C-1000]], up until 1979. It has a bore of 4.1875 inches. During that period, it powered almost all Chrysler New Yorker and all Imperial models, and was also available on the lesser Chryslers, [[Dodge Polara]], [[Dodge Monaco]], and [[Plymouth Fury]] as an alternative to the B-block 383 and the [[Chrysler A engine|A-block 318]]. It was also fitted to some European cars such as the later [[Facel Vega Facel II]].

In the 1959 Chrysler 300E, the 413 wedge was fitted with inline dual four-barrel carburetors; it was factory-rated at ((convert|380|bhp|kW|0|abbr=on)) at 5,000 rpm and ((convert|525|lbft|Nm|0|abbr=on)) at 3,600 rpm.<ref name="Atherton">((cite book|title=Mopar Performance |last=Atherton |first=Larry |publisher=S-A Design Publishing |year=1978))</ref> In 1960, a long-tube ram induction system was made standard on the Chrysler 300. It continued as standard on the 1961 300-G, and remained on the option sheets for Chrysler 300s through 1964. In 1962, a special version known as the "[[Max Wedge]]" was made available for drag racing and street use; this version produced ((convert|420|bhp|kW|0|abbr=on)) at 5,000 rpm.

===426 Wedge===
[[File:1966 Dodge Charger (5184677542).jpg|thumb|1966 Dodge Charger engine bay]]
Not to be confused with the [[Chrysler Hemi engine|426 Hemi]], the ((convert|426|cuin|L|1|abbr=on)) RB was a wedge-head RB block with a ((convert|4.25|in|mm|abbr=on)) bore. The 426 Wedge served as Chrysler's main performance engine until the introduction of the 426 Hemi. It was initially offered as the "non-catalogued" option S42 in Chryslers (the number of such produced is uncertain), offered with ((convert|373|or|385|hp|0|abbr=on)) via a single 4-barrel carburetor (11.0:1 or 12.0:1 [[compression ratio]], respectively), or ((convert|413|or|421|hp|0|abbr=on)) via ram-inducted dual four-barrel carburetors (with the same compression ratios).<ref>((cite journal|journal=Collectible Automobile |date=December 1994 |page=57 |title=1960-62 Chrysler "Positively No Jr. Editions" |first=Jeffrey I. |last=Godshall))</ref> For 1963, horsepower ratings would slightly increase (see below), and it became optional in [[Chrysler B platform|B-bodied]] Dodges and Plymouths. After 1963, it would be used only in Dodges and Plymouths.<ref>((cite book|last=Flory, Jr. |first=J. "Kelly" |title=American Cars 1960–1972 |publisher=McFarland & Coy |year=2004 |page=220))</ref>

The Max Wedge was a race-only version of the 426 Wedge engine offered from the factory. Known as the Super Stock Plymouth and Ramcharger Dodge, the Max Wedge featured high-flow cylinder heads developed through state-of-the-art (at the time) airflow testing.<ref name="Atherton"/> They had ((cvt|1+7/8|in)) exhaust valves, which required the cylinder bores to be notched for clearance. The blocks were a special severe-duty casting with larger oil-feed passages than other RB engines, and the blocks were stress-relieved by the factory. Induction came by means of a cross-ram intake manifold tuned for peak power above 4000 rpm and two Carter AFB-3447SA 4-barrel carburetors. The Max Wedge also included high-flow cast-iron [[exhaust manifold]]s that, on the later versions, resembled steel tube headers. The Max Wedge was factory rated at ((convert|415|or|425|bhp|kW|0|abbr=on)) (depending on compression), and ((convert|480|lbft|0|abbr=on)) at 4400 rpm.

Before the end of the 1963 model year, Chrysler introduced the Stage II Max Wedge with improved combustion chamber design and an improved camshaft. The last performance year for the Max Wedge came in 1964 with the Stage III. The factory-advertised power rating never changed despite the Stage II and III improvements.

A ''426 Street Wedge'' block was also available in 1964 and 1965. It bears little relation to the Max Wedge except for basic architecture and dimensions. The Street Wedge was available only in [[Chrysler B platform|B-body]] cars (Plymouth and Dodge) and light-duty [[Dodge D Series]] trucks. It was an increased-bore version of the standard [[Chrysler New Yorker|New Yorker]] 413 single 4-barrel engine.

===440===
[[File:SC06 1971 Plymouth 'Cuda 440 engine.jpg|right|thumb|440 6-Barrel RB V8 in a 1971 [[Plymouth Barracuda]]]]

The ((convert|440|cuin|L|1|abbr=on)) RB was produced from 1965 until 1978, making it the last version of the Chrysler RB block. It had a light wall construction, precision cast-iron block, with iron heads and a bore of ((convert|4.32|in|mm|1|abbr=on)), for an overall [[Engine displacement|displacement]] of ((convert|440|CID|L|1|abbr=on)).<ref>((cite book |title=World Cars 1981 |publisher=The Automobile Club of Italy/Herald Books |editor-last=Lösch |editor-first=Annamaria |page=234 |year=1981 |isbn=0-910714-13-4 ))</ref>

From 1967 to 1971, the high-performance version was rated at ((convert|375|bhp|PS kW|0|abbr=on)) (((convert|370|bhp|PS kW|0|abbr=on)) in 1971) at 4,600 rpm and ((convert|480|lbft|Nm|0|abbr=on)) at 3,200 rpm of [[Torque#Machine torque|torque]] with a single 4-barrel carburetor,<ref>((cite web|url=https://www.carfolio.com/specifications/models/car/?car=284515|website=carfolio|title=Dodge Charger R/T, 1969 MY XS29|access-date=July 11, 2018))</ref> and from 1969 to 1971, the highest-output version had an intake setup with 3×2-barrel [[Holley Performance Products|Holley]] [[carburetor]]s ("440 Six Pack" for Dodge, "440 6-BBL" for Plymouth) producing ((convert|390|bhp|PS kW|0|abbr=on)) at 4,700 rpm (((convert|385|bhp|PS kW|0|abbr=on)) in 1971) and ((convert|490|lbft|Nm|0|abbr=on)) at 3,200 rpm of [[Torque#Machine torque|torque]].<ref>((cite web|url=http://www.automobile-catalog.com/car/1970/2697500/plymouth_road_runner_440_6-bbl_hardtop_4-speed.html|website=automobile-catalog.com|title=1970 Plymouth Road Runner 440 6-bbl Hardtop 4-speed|access-date=June 24, 2018))</ref>

In 1972, changes were made to the [[Horsepower#Society of Automotive Engineers/SAE International|horsepower ratings]] of vehicle engines from gross (engine only, without air cleaner, exhaust system, alternator, or other power-consuming components) to net (with alternator, air cleaner, mufflers, and other vehicle equipment installed). The new rating system produced lower, more realistic numbers for any given engine. At the same time, [[Vehicle emissions control|emissions regulations]] were demanding cleaner exhaust. Engines including the 440 were made with reduced compression, modified cam timing, and other tuning measures to comply with the newly tightened emissions regulations. The 1972 440 produced ((convert|335|bhp|kW|0|abbr=on)) (gross) at 4400 rpm; the new net rating was ((convert|225|hp|kW|0|abbr=on))—which very closely coincided with period German [[DIN]] ratings and [[TÜV]] measurements.

The high-output 440 (4-barrel/mild cam/dual exhausts) was marketed as the ''Magnum'' in Dodges, the ''Super Commando'' in Plymouths, and the ''TNT'' in Chryslers. From 1972 to 1974, the engine (detuned to run on unleaded gasoline) was rated at ((convert|280|hp|kW|0|abbr=on)) net, and dropped in horsepower each year until 1978, when it was rated at ((convert|255|hp|kW|0|abbr=on)) (in police specification) and limited to Chrysler New Yorkers, Chrysler Newports, Dodge Monaco Police Pursuits, and Plymouth Fury Police Pursuits. It was also available in marine and heavy-duty commercial applications until that year.
