The Small Block V8 of the 1950s Turned into a Modern Day Cash Cow for GM
When GM first introduced the small block V8 engine in 1955 they had no idea how it would change the nature of car sales. Trucks were a secondary business in the 1950s. No one knew exactly where those truck sales were headed. Farmers and construction workers needed a good truck, but the general public was focused on cars and that business was growing rapidly. Remanufacturedenginesforsale.com has Fully Remanufactured GM 5.3 Liter Vortec for Sale below dealer cost.
A V8 engine back in the 1950s was a sign of power and car class. The 6-cylinder engines still didn’t have the power to move those chunky bodies, and 4-cylinder engines were unheard of in the States. The US car people didn’t think 4-cylinder engines would power a car, even though the Europeans and Japanese were using them.
The auto industry has reinvented itself over the years and the thinking process and buying habits of average consumer have dramatically changed. Every car manufacturer is in the truck business today. GM still holds a prominent place in the minds of the truck buying public thanks to the evolution of the 5.3 litre Vortec engine, which was first introduced as the Vortec 5000 L30. The L30 is a 220 horsepower with 220 ft-lbs of torque at 4600 rpms V8 engine.
