Howards Cams, Rattler Hydraulic Roller Camshaft, Chrysler B/RB, 235/243 @ .050, .530/.530, 109 LS

Howards Cams Rattler Hydraulic Roller Camshaft

The best of both worlds. The performance of a high lift roller cam with the easy maintenance and durability of a hydraulic. These Rattler Cams are for street enthusiasts who want the classis exhaust sound, but also want true performance to go with it. Great for street/strip and bracket racing too. Reduce friction, increase torque and horsepower. They give you the performance and throttle response you expect from a performance cam. Rockwell checked to ensure the highest quality control standards available anywhere. If you want both sound and performance, you need a Howards Cams Rattler. 
Note: to get the best exhaust note, you should use a good dual exhaust system without a cross-over. A cross over will add minor performance, but mellow the exhaust tone.
