Howards Cams MC721141-08 Hydraulic Flat Tappet Max Certified Camshaft and Lifter Kit

The Howards Cams MC721141-08 is a Max Certified Hydraulic Flat Tappet Camshaft and Lifter Kit engineered for Chrysler 383–440 big block engines. Designed using Howards Cams' computer-aided cam profiling process, this kit delivers strong low- and mid-range horsepower and torque across a broad RPM range, making it an excellent choice for street, street/strip, and bracket racing applications.
