I found these specs on the Pantera.  My guess would be that it was detuned to run with unleaded fuel.   Or he was just toying with me.  I didn't mean to imply that it's a weak car or something.  I was just relaying my only encounter with one.  
 
I was really impressed that the driver still drove it with gusto unlike people with their brand new Vettes.  It would be a really cool car to put a modern, fuel injected engine in.
