At one point, BDM devided the product line into "core"and "Platinum" models.
The Husky was in the core group. Initially the core bikes had S&S engines and the Platinum bikes had TP engines.
Best weay to tell what cam is in the bike is to see if you have roller rockers. If you have roller rockers, you have a .600 cam. If you have standard rocker arms, you have a .520 cam.
