#/4 race cam = Old fart who is living dreams of the past.
It's from back in the day when it was all, as Smokey used to say, "monkey see, monkey do." If you wanted a fast car, you called the speed shop and got a 3/4 or full race cam. A full race cam was what the NASCAR boys would run and the cam specs varied wildly from cam to cam. It was whatever the manufacturer thought was good for max power. 3/4 was just a little milder and so on down the line. To use terms like that when every cam comes with a card that lists the specs is just telling every one, "I have no idea what is in this engine."
