Raising an engines compression ratio allows the engine to extract more energy from the fuel it burns, improving both power and fuel economy. More-or-less stock Rocket 88s continued winning their classes at the drag strip well into the 1950s. Some Oldsmobile employees detested that name, but it remained strongly associated with Oldsmobile well into the 1960s. 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. The main distinguishing features of this engine were a slightly different camshaft profile from the standard ultra high compression engine and factory dual exhaust. At the risk of shameless self promotion, you might also be interested in the recently revamped article on the early Hydra-Matic, which most Oldsmobiles of that vintage had. Until 1951, Oldsmobile offered a choice of fastback and notchback body styles, as well as the convertible.

Shortly after the war, Ketterings engineers built an experimental 181 cu. The following year, 88s won 10 out of 19 Grand National races and set a new speed record at Daytona. 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). That July, Burrell was promoted to chief motor engineer for the division. He saw the potential in an engine design offering increased compression. The LG8 was a modern 307cuin (5.0L) High-Output derivative of the LV2 produced from 1983 to 1987. The engine is also known for its reliability, smoothness and quietness. California residents also have the Right to Opt-Out of the sale of their personal information see the Do Not Sell My Personal Information page.

With an overall length of 202 inches (5,131 mm) and an overall width of 75.2 inches (1,910 mm) on a 119.5-inch (3,035mm) wheelbase, the 88 was hardly a small car even by American standards and it tipped the scales (in this body style) at almost 3,800 lb (1,717 kg) with Hydra-Matic, but its Rocket V8 would leave Pontiacs elderly straight eight or Chevrolets Stovebolt Six for dead and the Oldsmobile name carried more prestige than Pontiac or Chevrolet.

The Buick version of the 215 V8 went on to become the well known Rover V8, which still remains in limited production, utilizing the Buick-style pistons, heads, and valve train gear. Bore was 3.75in (95mm) and stroke was 3.4375in (87.31mm). Still, the same quandary exists that faced Gordon Burrell and Jack Gordon in the late forties: New technologies in this case, direct injection, turbocharging, and even hybrid powertrains can benefit both performance or fuel economy and emissions, but one still almost always wins out over the other. 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 idea of Olds as the import-fighter brand obviously had its own problems.) For engines built during the first part of 1955, the 324 skirted pistons had a reputation for failing due to the cast aluminum skirt separating from its steel interior brace. Following the Automobile Manufacturer Association ban on factory supported racing, power ratings went down for the 1959 and 1960 88 models: 270hp (200kW) and 390lbft (530Nm) for 1959 and 240hp (180kW) and 375lbft (508Nm) for 1960.
