BS. The Buick Skylark and Old's Starfire of the early sixties had all aluminum 215 c.i. V8s. Some came with turbochargers.
Those motors had cooling problems because owners couldn't get it through their thick heads that you shouldn't fill the radiator from the garden hose. (water jackets would corrode and the motor'd overheat)
When GM discontinued the motor, it sold the tooling to Rover and is the basis of the V8's Rover still uses.

Um, Rover went bankrupt and closed a number of years ago.
