Ahhhhhh…the old “there are so many it must be good” theory.
Not really. Like the small block Chevy, GM produced a piece of garbage and the aftermarket spent many, many times more R&D on that junk than GM did.
Mass production doesn’t mean quality. Or even a good product. It just means a lot of **** was made and the consumer would rather have **** than a donut. Damn near every time.
