Howards Cams, Rattler, Hydraulic Flat Tappet Camshaft & Lifter Kit, Chev BB Mark IV 235/243 @ .050, .553/.545, 109 LS

Howards Rattler Cams Hydraulic Flat Tappet Camshaft & Lifters
Howards Rattler Cams are now available as cam and lifter sets. They are for street enthusiasts who want the classis exhaust sound, but also want true performance to go with it. It’s also great for street/strip and bracket racing. They give you the performance and throttle response you expect from a performance cam. These sets offer sizable torque, horsepower, and rpm increases at an affordable price. If you want both sound and performance, you need a Howards Cams Rattler and a set of premium hydraulic flat tappet lifters. 
Note: to get the best exhaust, you should use a good dual exhaust system without a cross-over. A cross over will add minor performance, but mellow the exhaust tone.
