Cam a cam wear out?

Lookin' at a car, owner says his mechanic say the Cam is worn out because her ran with too little oil. Claims there is no other damage.

Haven't actually been to see it yet so don't know how it runs. Owner says it runs fine but when you floor it, it chokes.

Is this at all plausible?

I must admit this is a chebby I'm lookin' at.

Thanks.
