Howards Cams Big Bottle Cams Nitrous Oxide 4/7 Swap Firing Order Mechanical Roller Camshaft
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. 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.
