The 303-cubic-inch (5.0L) engine had hydraulic lifters, an oversquare bore:stroke ratio, a counterweighted forged crankshaft, aluminum pistons, floating wristpins, and a dual-plane intake manifold. Shortly after the war, Ketterings engineers built an experimental 181 cu. Ketterings team demonstrated that the higher compression ratio boosted power and gas mileage by nearly 30%. (The idea of Olds as the import-fighter brand obviously had its own problems.) Bore was up to 4.0in (100mm) and stroke was increased to 3.6875in (93.66mm) for 371cuin (6.1L). 49 rocket 88 was my first car back in 1964.

There were 64 1st Gen sold in the last 5 years. A cheaper solution (pioneered by Buick back in the days before General Motors was formed) was to leave the camshaft in the block, as in a flathead engine, but add long metal pushrods to allow the camshaft to actuate the valves remotely. The 307 "Y" produced 148hp (110kW) and 250lbft (340Nm) in 1980-1984 models and 140hp (100kW) and 250lbft (340Nm) in 1985-1990s. The L34 used a 4-barrel carburetor and produced 160170hp (120130kW) and 275ftlbf (373Nm). Adding turn signals, backup lights, windshield washers, and heater tacked an additional $112 to the price these items wouldnt be standard for several more years. Naturally, GM was extremely interested in the potential of high-compression engines for passenger cars, but there were two hold-ups. 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.

The OHV V8 would dominate the American industry well into the 1980s, resulting in some staggeringly powerful engines whose output has only recently been surpassed. [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.

Performance modifications included a "hot" camshaft (in reality, just a camshaft used in various applications during the '70s with .440"/.440" lift and 196/208 duration at .050"), stiffer valve springs, a larger vibration damper (same as all '73-'79 350s, 403s, and 455s), a Y-pipe dual-outlet exhaust system, and richer secondary metering rods in the carburetor. spark ignition engine for high-compression studies. By 1952, the 88 was growing inexorably bigger and although Oldsmobile engineers had little trouble getting more power out of the Rocket engine by 1955, it boasted 202 gross horsepower (151 kW) newer, lighter cars soon surpassed its performance.

As is the case with all pre-1972 American passenger car engines, published horsepower and torque figures for those years were SAE "Gross," as opposed to 1972 and later SAE Net ratings (which are indicative of what actual production engines produce in their "as installed" state - with all engine accessories, full air cleaner assembly, and complete production exhaust system in place).

In short, the flatheads breathing ability is only mediocre. Many modern engines deal with this problem by placing the camshaft in the cylinder head along with the valves (an overhead cam (OHC) engine), but there still has to be some way for the crank to drive the camshaft. Most 394s used 2-barrel carburetors, but special high-compression 4-barrel versions were available starting in 1961. If the fluid reservoir was empty, a complex double-float and valve assembly in the Turbo-Rocket Fluid path would set a second butterfly (positioned between the throttle butterfly and the turbocharger) into the closed position, limiting the amount of boost pressure.

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. Output was 185hp (138kW) and 320lbft (430Nm). 425 motor, super rocket. In any case, the early postwar period saw the emergence of the California customizing/hot rod scene; the advent of the fiberglass kit car body manufacturers such as Bill Tritts Glaspar (Tritt was retained briefly by GM as a consultant in 1951 when they were considering building a lightweight fiberglass-bodied sports car); and the birth of modern motorsport in the US with the founding of the SCCA and the advent of road racing as the most popular form of competition. The Rocket 88 model name was dropped after 1957. Output for 1983-1985 was 180hp (130kW) and 245lbft (332Nm). By late 1956, many Olds dealers learned about the problem. The Buick version was rated at 200hp with an 11:1 compression ratio. 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.

These were wedge-head engines with a unique combustion chamber that resulted from a valve angle of only 6. The introduction of the "Rocket 8" V-8 for the 1949 Oldsmobiles was perhaps the pinnacle of his achievements, incorporating in its overhead-valve design such features as five main bearings,. 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.
