Talked to Owen our mechanic. Those numbers are just casting numbers for a stock cam. When a cam is reground it is welded up & reground. Look on the side of the lobes for any weld build up. If none there it is probably stock. Take a caliper & measure the lift. Then compare it to stock specs & Megacycles specs. Should be able to tell just from the lift what it is.
