If I recall, It's really close. I want to say 52-48, but I'm not sure.

You are probabaly thinking of 2 unsuited overcards against a pair.

AJo has an equity of about .5976, according to PokerStove. The exact advantage depends on the relations between the suits. Here are some particular examples of AJo vs. KQo from Two Dimes:

In many other cases, the advantage of the hand with the overcard is lower. These are extreme examples:

4/images/graemlins/heart.gif 3/images/graemlins/heart.gif 0.538

(I didn't realize it was possible for the lower hand to be the favorite. It is rare.)

The advantage can be slightly higher than AJo vs. KQo:
