I'm trying to find out if this guy is on the up and up. I have a chance to buy a Hot Cam still in the box. The box says ACD# 24502586, GM# 24502586 which I confirmed is right. On the end of the cam it says "586 FM70" "092 03R". Numbers don't match the box. Is this the right number for the cam? The yellow tag on the box says 2450-2586 Camshaft HYD STE. I'm assuming that the 586 on the end of the cam has something to do with the ACD# since this number does include 586. Any help would be appreciated. Thanks.[8D]
