Howards Cams 4/7 Swap Camshafts
Howards Cams 4/7 swap camshafts are ground in-house, so each cam is manufactured on precision cam grinding machines—not re-boxed like other companies. These 4 and 7 swap firing order cams feature a high-grade race quality core that changes the engine's firing order pattern to create more power. Howards Cams packages and ships most of their cams in a unique, reusable, high-impact-plastic case to ensure that your camshaft reaches you in nothing less than perfect condition. Get the competition 4/7 swap camshaft from Howard Cams designed for your application today!
