The Important Facts of Pontiac's Superior Performance

Dating to 1956 and produced by Jam Handy on behalf of General Motors, "The Important Facts of Pontiac's Superior Performance" promotes the new Strato-Streak engine and StratoFlight Hydra-Matic transmission. The Strato-Streak was a V8 engine produced by Pontiac from 1955 to 1957. It was initially designed for a 1953 introduction, but its debut was delayed until 1955. The engine was part of a larger effort by Pontiac to modernize their lineup and compete with other manufacturers.

00:00 The presentation introduces the reasons for Pontiac's power in 1956, focusing on the Strato Streak engine and StratoFlight Hydra-Matic transmission.
0:32 The film highlights the Strato Streak engine and StratoFlight Hydra-Matic transmission as key components of Pontiac's performance.
0:51 The features of the 1956 Strato Streak engine are detailed, including its size, displacement (316.6 cubic inches), compression ratio (8.9:1), and horsepower (227 hp).
1:24 The engine's design for smooth and efficient combustion is explained, including the machined wedge-shaped combustion chamber.
1:33 Additional engine features like aluminum-treated intake and exhaust valves for protection and fuel efficiency are described.
1:51 The film discusses the new larger spark plugs, 12-volt electrical system, and a fully enclosed starter motor for improved durability and all-weather performance.
2:10 The new high-lift camshaft, designed for more efficient engine breathing, power, and longer engine life, is explained.
2:22 The inclusion of Pontiac-approved features like the harmonic balancer (now matched with another in the transmission) for smooth operation is mentioned.
