Are you high? Other than the nylon cam gear, the Olds 350 ran forever with basic maintenance. They didn't eat valve guides and cams like brand c from that era. Even the later windowed blocks were very durable if not pushed hard.
It's a joke if you couldn't tell.
The $$$ portion refers to the fact that olds/buick/pontiac are, beyond any dispute what-so-ever more expensive than chevy multiple times over.
Not that the motors themselves require constant attention and maintenance
