What year was the first Chevrolet V8 produced?

Chevrolets first V-8 was made in 1916 and they even sold a few in 1917. but, they weren't very efficient and weighed a lot so they were scrapped. The first mass produced Chevy V-8's wer introduced in 1955. They were 265 cubic inches and rated at 150 horsepower. Couple of little known facts about them. 1. They didn't use an oil filter. 2. They were so well made that they took forever to break in and owners complained because they used excessive oil. The fix. believe it or not was Bon Ami, a mild scrubbing powder. They put it in the oil to cause the engine to wear a little faster so the rings would seal. 3. They pumped oil up to where you would expect to find an air filter and used an oil bath to filter the air before it went to the carb. 4. The exhaust manifold on the left side dumped out the front into a tail pipe that wound it's way around to the other side. The reason they did that was to clear the steering box.
