with Oakland ceasing production in 1932. Pontiacs were also manufactured from knock-down kits at GM's Japanese factory at Osaka Assembly in Osaka, Japan, from 1927 until 1941. Pontiac produced cars offering , (3.25x3.75 in, 82.5x95mm) L-head straight-six cylinder engines in the Pontiac Series 6-27 of 1927; its stroke was the shortest of any American car in the industry at the time. The Series 6-27 sold 39,000 units within six months of its appearance at the 1926 New York Auto Salon, hitting 76,742 in 12 months. The next year, 1928, it became the top-selling six-cylinder car in the U.S., as well as ranking seventh in overall sales. When the Wall Street Crash of 1929 occurred in September, both Pontiac and Oakland sales dropped dramatically and because Oakland was the more expensive, GM leadership decided that Pontiac should remain. 1932 was the first year for the Pontiac Series 302 V8. The 1932 V8 had an oversquare bore and stroke of x displacing with a compression ratio of 5.2:1. Horsepower was rated at @3200 RPM using three main bearings, solid valve lifters and a Marvel one-barrel carburetor. Unusually, Pontiac switched to the straight-eight for 1933 until it was replaced in 1954. As the economy began to recover, by 1933, Pontiac had moved up to producing the least expensive cars available with straight-eight engines. This was achieved by using many components from the six-cylinder Chevrolet Master, such as the body. The Pontiacs were differentiated by a large chrome strip on the top and center of the front hood that Pontiac called the "Silver Streak". Only eight-cylinder engines were offered in 1933 and 1934, displacing rated at . In 1935, Pontiac shared the "torpedo" body appearance with the LaSalle and the Cadillac Series 60, just prior to its being used by Chevrolet, earning some media attention for the marque. At the 1939 New York World's Fair, a 1939 Deluxe Six was displayed with body panels made entirely from plexiglass. An unusual feature of the "torpedo"-bodied exhibition car was that, with the push of a button, the front half of the body would open showing the engine and the car's front seat interior. A major change occurred in 1937, when all Pontiac models except the new station wagon began using the all-steel B-body shared with Oldsmobile, LaSalle, and small Buicks. A new stronger X frame had a Hotchkiss drive using a two-part drive shaft. The eight-cylinder
