Some L-head straight-eights were MORE powerful than early OHV V-8s, although they were getting to the limit of their potential, at least in states of tune that were still reasonably streetable. Assuming your car has its original engine, its the version Oldsmobile called the Skyrocket, which was differentiated from the base Rocket by its four-barrel carburetor and gross ratings of 330 hp and 440 lb-ft of torque. You can hide the "Support Ate Up With Motor" box and prevent the loading of its embedded content by going to the "Consent Management" tab and switching the "Allow PayPal Button" toggle to "OFF." 442 . The original Oldsmobile V8 was to have been marketed as "Kettering Power" after chief engineer Charles Kettering, but company policy prohibited the use of his name. The turbocharger fitted to the V8 engine was a small-diameter Garrett T5 model with integral wastegate, manufactured by Garrett AiResearch, and produced a maximum of 5psi (34kPa) boost at 2200rpm. Full instrumentation is standard Olds had not yet succumbed to the allure of warning lights. For the Rocket 88, Oldsmobile came up with a 303 cubic inch V8 capable of a maximum 135 hp and 283 lb-ft of torque. [5], This engine was used in GMC heavy trucks as the "370" of 232 gross HP at 4200 RPM and torque 355 gross lbs-ft at 2600 RPM from 1957 to 1959.It had hardened valve seats and other features for heavy duty usage. Power for the base engine was up to 315hp (235kW), even though compression was down a quarter point, to 9.75:1.[9]. We think it was probably just as well that the proposed ultra-premium fuels never materialized; as it was, increasing the octane rating of pump gasoline from the 70 RON of typical mid-forties regular fuel to the 98 RON level of later super-premium fuel increased the amount of lead in each gallon by more than 40%, with significant public health consequences. (4,705 cc) and were designed to take advantage of research that had been done by GM Research VP Charles Kettering on high-compression engines (of which well have more to say below). Some of the photos in our Avanti article, and those of our story on the Packard One-Twenty, were taken at the same time. Im not sure about the early Hydramatics but later ones, 54-56 you put in reverse to park.

Many were shared among other divisions, but each design was unique: GM later standardized on the later generations of the Chevrolet design: Northway sourced Oldsmobile Flathead V8 (1916-1923). Most of these engines were very similar, using the same bore centers and a 9.33in (237mm) deck height, raised on "big-block" versions to 10.625in (269.9mm). What these activities have most in common was that there was an awful lot of engine-swapping going on. This very open and flat chamber was fuel efficient and had lower than average emissions output. 8-9; Arch Brown, Similar But Different: 1949 Cadillac vs. 1949 Oldsmobile 98, Special Interest Autos #149 (September-October 1995), reprinted in The Hemmings Book of Oldsmobiles: driveReports from Special Interest Autos magazine, eds. I am almost 79 now and remember that like it was yesterday. There will typically be several such cookies, each beginning with "gdpr" (e.g., gdpr[allowed_cookies], gdpr&5Bprivacy_bar&5D, and gdpr[consent_types]). First, their volumetric efficiency is poor. The practice of keeping model names alive even though applied to a vehicle with little in common with the original seems to annoy no one but me, [example Impala], why not keep division names alive and apply them to selected models. Bore was up to 4.0in (100mm) and stroke was increased to 3.6875in (93.66mm) for 371cuin (6.1L). An engines static compression ratio is the ratio of the swept volume of each cylinder to the volume of the combustion chamber; the higher the ratio, the more the engine compresses its fuel mixture before combustion. In an OHV engine, by contrast, the valves are a fair distance away from the crankshaft, which makes operating them far more complicated. Bore was up to 4.125in (104.8mm) for the largest first-generation Rocket, the 394cuin (6.5L). Prior to the advent of the 1949 Cadillac and Olds engines, many (though by no means all) U.S. engines were L-head, or side-valve, design. "Alternative Engines: Part 2--Buick V8", in, Davis, Marlan. Overhead valves did not suffer the same problem, which gave them the potential for much higher compression ratios. An 88 also won the first grueling Carrera Panamericana, the 2,176-mile (3,500-km) Mexican Road Race. Displacement swelled from 303 Ci or 5 liters all the way to the gargantuan 455 Ci 7.5 liter V8 in the early 70s. Me at the age of 70 in the back seat with a 21-year-old blond.

Thanks for the great write up on the history of one of the most influential engines in the automobile industry! One by one, every other American manufacturer brought out its own OHV V8 engine: Chrysler and Studebaker in 1951; Lincoln in 1952; Buick and Dodge in 1953; Ford and Mercury in 1954; Chevrolet, Pontiac, Plymouth, and Packard in 1955; and AMC in 1956. This 1955 oldsmobile deluxe 88 is a 2 door holiday coupe.. 2 tone twilight blue and polar white colors with ivory and blue interior. Instead, influenced by the Space Race between the United States and the USSR, the legendary Rocket was born, available in Oldsmobile's 88, Super 88, and 98 models. For anyone interested the 1950 Mexican road race where 12 Olds 88s entered and 10 finished, eight of the 10 were beaten by a flathead Nash. Our sources for this article included the Auto Editors of Consumer Guide, Encyclopedia of American Cars: Over 65 Years of Automotive History (Lincolnwood, IL: Publications International, 1996); John R. Bond, Car of the Year: The 1949 Cadillac, Motor Trend November 1949, reprinted in Cadillac Automobiles 1949-1959, ed. It has gained popularity among young muscle car lovers.

Two distinct versions of the 400 CID engine were made: The 1966-1967 4-4-2 400cuin (6.6L) V8 was a short stroke engine which featured B and C cast large-valve cylinder heads and hydraulic lifters of larger diameter, as well as push-rods of different length and diameter than the standard Olds Rocket V8. Comments may be moderated. So, its not particularly surprising that a highly tuned flathead Ford would be stronger than a stock 1950 Olds 303. The 455 big block Olds V8 was replaced in 1977 with the 403cuin (6.6L) small block, which used a 4.351in (110.5mm) bore, the largest ever used in a small-block V8, with the Olds small-block standard deck and 3.385in (86.0mm) stroke. All generation-2 small-block Olds V8s used a stroke of 3.385in (86.0mm). Compression ratios of 9.0:1 at 310hp (230kW) or 10.25:1 at 360hp (270kW) were available in the U.S. A special 1965-1967 425cuin (7.0L) V8 was the Starfire engine. The 403 is fundamentally the exact same block as an Oldsmobile 350 V8, however it features a larger bore. The high-compression four-barrel 394 cu. The 307 "Y" produced 148hp (110kW) and 250lbft (340Nm) in 1980-1984 models and 140hp (100kW) and 250lbft (340Nm) in 1985-1990s.

I have read several histories of the 1949 Oldsmobile and Cadillac V-8s, but never seen Bouvy mentioned. 1956 Oldsmobile 88 Rocket The engine design for the Rocket 88 came from GMs chief researcher, Charles Kettering. The final 1990 configuration was rated at 140hp (100kW) at 3200 rpm and 255lbft (346Nm) of torque at 2000 rpm. In practice, owners who did not regularly drive hard enough to engage the front and rear carburetors experienced problems with the linkage and carburetor throats becoming clogged, and some J-2-equipped cars had the front and rear carburetors removed and blocked off. But I can block the blow by coming off the back of the block and it runs great. (Im not entirely sure why H-M did not, actually.). The real standard of the world. I forgot this on one occasion when I was attempting to jump start my 55 Olds; after getting the car rolling backwards, I was rewarded with nothing more than a ratcheting sound when I shifted from N to R. The engine did not rotate and the car did not start. Ketterings team demonstrated that the higher compression ratio boosted power and gas mileage by nearly 30%. The desire to raise compression ratios had prompted Kettering and his staff to develop tetraethyl lead as an octane-boosting gasoline additive in the early twenties (as discussed in greater detail in our article on the 1970-1981 Chevrolet Camaro), but the research staff had been working to raise compression ratios even higher. Each engine in this generation is quite similar with the same size block and heads. Simplified diagram of the cylinder of a wedge-head OHV engine. 1988), pp. ), Diagram of a typical pushrod/rocker-arm layout of an overhead-valve engine.

Unless youre building a rod, its often worth it to spend more upfront for a car thats in better condition. Oldsmobile engineers originally wanted to call this the Kettering Engine, after GM research vice president Charles Kettering, whose work on high-compression engines helped to inspire it. The heavily domed hood would continue through 1953. The Buick version was rated at 200hp with an 11:1 compression ratio. (4,214 cc) L-head straight eight. 26-31; Roger Huntington, 1965 Engines, Motor Trend Vol. Off.).) in. 4 speed hydromantic transmission. Put the petal to the metal and go man go! The grilles under the headlights of this 1950 Oldsmobile Rocket 88 are for the ventilation system, replacing the traditional pop-up cowl vent. In short, the flatheads breathing ability is only mediocre.

Based on the Cadillac Northstar engine, this 4.0-liter engine, called Aurora, was a DOHC design with four valves per cylinder. Its a super 88 sedan 4 door. Its a true barn find. The idea of keeping the brand names on a model-specific basis is not illogical (although again its contrary to current brand management philosophy), but it would present all manner of practical problems, not least that it would invite the ire of people who had previously paid money for a sales franchise for that brand. As an aside, the Oldsmobile was bought by doctors, lawyers, bank managers, shop owners, construction entrepreneurs and the like. (We have now DISCONTINUED our use of Google Analytics tracking on this website; see the "Online Tracking" section of the Privacy Policy for more information.) Naturally, GM was extremely interested in the potential of high-compression engines for passenger cars, but there were two hold-ups. The super-fuels the engineers wanted would probably have added even more. [19] The 403 was never featured with a manual transmission and the crank was never manufactured for a pilot bearing. ), When you list the OHV Detroit engines that came along after the Rocket, the DeSoto Hemi of 1952 and Plymouth Poly of 1956 may merit mentioncant recall if the 1955 Packard V8 got its curtain call. Oldsmobiles first OHV V8, dubbed the Rocket engine, had a 3.75-inch (95.3mm) bore and a 3.44-inch (87.3mm) stroke, compared to 3.25 inches (82.6mm) and 3.88 inches (98.4mm) respectively for the straight eight the Rocket replaced. The optional heater-defroster cost $85 that year, the optional base radio $96. 1949 Oldsmobile Rocket 88 The Oldsmobile 88 was introduced in 1949 as a replacement for the 70 series. We are known for our high quality,attention to detail and meeting our customers goals. Two-door fastbacks, like this one, were known as Club Sedans; the four-doors were called Town Sedans. [12] The Oldsmobile engine was very similar to the Buick engine, but not identical: it had larger wedge combustion chambers with flat-topped (rather than domed) pistons, six bolts rather than five per cylinder, and slightly larger intake valves; the valves were actuated by shaft-mounted rocker arms like the Buick and Pontiac versions, but the shafts and rockers were unique to Oldsmobile. Have never been an American car guyI cut my teeth on old British roadstersbut I have to say I thoroughly enjoyed your well-written, informative article on the history of the Rocket 88. $300.00.

About six weeks after he started work, Burrell showed his designs to Oldsmobiles chief engineer Jack Wolfram and Oldsmobile general manager Sherrod Skinner. It used a very oversquare 4.057in (103.0mm) bore and Oldsmobile small-block standard 3.385in (86.0mm) stroke for 350cuin (5.7L). Olds veterans claimed the Burrell group was completely unaware of the Cadillac project until quite late in the development of the Oldsmobile V8. Additionally, the 403 had windowed main webs, which reduced the internal strength of the block in the crankcase area. They may persist for up to two years. The end of the Korean conflict sent the country in a foreign exchange crisis that lasted until the middle 90s, cutting imports and providing the basis for national production. Around the end of that year, the project nearly ground to a halt due to objections from Cadillac. Motor Trend (July 1950) mentioned getting 18.8 mpg at a steady 50 mph and a 1950 Olds entered in the Mobilgas Economy Run bettered 20 mpg. [21] It produced 110hp (82kW) net and 205lbft (278Nm). It was released one year earlier than the tall deck 425, and debuted the standard 3.385in (86.0mm) stroke; bore was 3.938in (100.0mm). The Oldsmobile Rocket 88 has a current value close to $96,250 at some auctions.

Oldsmobile was basically offering three full-size vehicles in 1949, but the 88 was a little bit special. PLEASE DON'T SUBMIT COPYRIGHTED CONTENT YOU AREN'T AUTHORIZED TO USE! Learn more. Like the test mules, the Rocket 88 was, in the parlance of a somewhat later era, a real bomb. Flathead engines are easy and cheap to manufacture, but they leave a lot to be desired when it comes to performance. The prototypes, which first ran in November 1946, were 287 cu. The Rocket, along with the 1949 Cadillac V8, were the first post-war OHV crossflow cylinder head V8 engines produced by General Motors. Original revolutionary Hydra-Matic SUPER DRIVE 3-speed automatic transmission, spare tire, and a couple of extra chrome wheel covers. The Generation II V8 ended production in 1990. in. To learn more about what information the Vimeo platform collects and how that information may be used, see the Vimeo Privacy Policy. Displacement was 259.5 cubic inches, with almost square bore and stroke. This car has the pushbutton radio, which cost about $96. It has been purported that there is a 403 Oldsmobile block and cast that has solid main webs that may have been equipped in vehicles such as the Pontiac Firebird equipped with a towing package, but there are currently no clearly documented surviving examples. edu/~wkovarik/ papers/fuel.html, accessed 30 May 2008, and Henry Ford, Charles Kettering, and the Fuel of the Future,' Automotive History Review #32 (Spring 1998), pp. I will let you know soon. . Sunday - Closed. From 1916 through 1922, the only Oldsmobile V8 was a 246.7 cid L-head of Model 47 with a 233.7 cid V8 that made 60 hp. Happy to see someone that not only mentions, but appreciates the early Olds. 98 J-2. To mitigate these problems, both Oldsmobile and Cadillac adopted an overhead-valve (OHV) layout. Unlike the 76, powered by a straight-six engine, the 88 came with a V8 under the. 303 Oldsmobile V8 parts in-stock with same-day shipping. 15-16 MPG is great even by modern standards, for a 300+ HP engine. Were Oldsmobiles ever sold in Brazil in any significant numbers? Cadillac used a distantly related engine which appeared in three different sizes through to the 1962 model year; though the Oldsmobile and Cadillac motors were not physically related, many lessons learned by one division were incorporated into the other's design, and the result were two engines known for their excellent power-to-weight ratio, fuel economy, and smooth, strong, reliable running. Cant wait to get my Wool Fedora and get it back on the road. However, my research has of necessity stretched back somewhat further than that and not just to the late 40s but, in tracing company histories, at least as far back as 1903 and the curved dash Oldsmobile. The Rocket-powered 98 was already a very respectable performer, so installing the new engine in the lighter body made for quite a hot number. Any interest in better fuel economy was quickly forgotten; gasoline was cheap and speed sold more cars than parsimony.

Where is the plate located? Every 307 used a four-barrel carburetor, which was a variant of the Rochester Quadrajet, usually the CCC (Computer Command Control) Quadrajet. Known variously as the Rockette, Cutlass, and Turbo-Rocket by Oldsmobile (and as Fireball and Skylark by Buick),[10] it was a compact, lightweight engine measuring 28in (71cm) long, 26in (66cm) wide, and 27in (69cm) high (same as the small-block Chevy),[11] with a dry weight of only 320lb (150kg). The 88 model remained in production for a whopping 50 years and over ten. Neither of GMs new OHV V8s had an exceptionally high compression ratio at first Oldsmobiles was 7.25:1, Cadillacs 7.5:1 but that was mostly a reflection of the low octane of the gasoline of the time. The 394 replaced the 371 in Super 88 and 98 cars for 1959 and 1960 and a detuned version was used in the 88 for 1961 and the Dynamic 88 for 1962-1964. Powered by the rocket 2bbl. You shared that mileage ranged from 12 MPG 18 MPG depending on the year. Revisions to the engine for 1986 included roller lifters with a slightly smaller camshaft (.435"/.438" lift and 194/210 duration at .050"), new heads with smaller, swirl-port intake runners, floating piston pins, and larger piston dishes for lower compression (8.0:1 v. 8.4:1). From 1950 through 1974, the 88 was by far the most lucrative line throughout the division, largely due to the entry-level versions like the 88 and the Dynamic 88. (. These were wedge-head engines with a unique combustion chamber that resulted from a valve angle of only 6. Flory, J. Note the quadrant for the Hydra-Matic atop the steering column. If anyone at GM had had doubts about offering the big engine in the smaller body, the sales alone would have been enough to convince them.
