I have an acquaintance who claims to be an engineer. I have my doubts.
Is there a listed registration of engineers with PE's?

Here's a page from TechCalcs.com with listings for
the licensing boards in all of the United States 
and occupied territories, which provides full
contact information and links to their websites:

I believe you'll need to know in which state he's registered. Here,
for example, you can check on the licensure of professional engineers
in West Virginia:
