Hydraulic Roller Camshaft and Lifter Kit 231/239 .535/.550 Lift

This retro-fit hydraulic roller camshaft is categorized as a high-performance street cam, intended for enthusiasts seeking enhanced power and drivability. This Voodoo series camshaft thrives with complementary upgrades, specifically recommending an improved intake manifold, carburetor, and exhaust system to maximize its potential. For optimal operation and to manage the camshaft's characteristics, a stall converter with a 2800 RPM rating is generally required, and a compression ratio of at least 9.5:1 is necessary for achieving peak performance. The kit includes the camshaft and matching lifters (#72334-16). Key specifications for this camshaft include advertised durations of 282 degrees for the intake and 290 degrees for the exhaust. At 0.050 inches of valve lift, the durations are 231 degrees (intake) and 239 degrees (exhaust). The gross valve lift measures .535 inches intake and .550 inches exhaust when used with 1.5 ratio rocker arms, and increases to .588 inches intake and .604 inches exhaust with 1.65 ratio rocker arms. The camshaft features a Lobe Separation Angle (LSA) of 110 degrees and an Intake Centerline (ICL) of 106 degrees. The valve lash specification is hydraulic for both intake and exhaust. The intended operating RPM range for this camshaft is between 2200 and 6200 RPM.
