All Howards™ Cams are ground at Howards Cams™, not reboxed like some cam companies. All Howards™ Cams use the highest-grade race quality cores available. All hydraulic and mechanical flat tappet camshafts are 100% Rockwell checked and Parkerized to ensure the highest quality control standards available anywhere. Howards™ Cams are manufactured on dedicated high precision cam grinding machines. Most Howards™ Cams are packaged and shipped in our unique, hard, high impact plastic reusable cases. This ensures that the high quality camshaft that went into the case comes out in the same condition, when delivered, as when it was packed.| Cam Part No. | Cam & Lifter Set Part No. | Duration IN |

All Howards mechanical roller cams are made from premium billet steel. Mechanical roller cams are designed and mainly used in full competition applications. Real race conditions are extremely punishing to the valvetrain and the camshaft. So why would you use a cast core? No matter how good the heat-treatment, a cast core (SADI) will not provide the performance or durability of an American steel billet cam. At Howards Cams we will not skimp on materials for higher profits.| Cam Part No. | Cam & Lifter Set Part No. | Duration IN |
