WARNING!!
• It is the responsibility of the engine builder or end user to check all clearances when using high lift camshafts.
• Pro Series Stage 3+ camshafts are not emissions legal.
• DO NOT use oversized valves.
• DO NOT increase overlap over specifications below.
• Improperly installed and degreed camshafts can cause catastrophic engine damage and failure.
• Camshafts will place greater stresses on valvetrain components and cause higher rates of wear.
• Installer should double check piston-to-valve clearance.
• MUST use high performance valve springs - recommend Skunk2 valve springs.
• Highly recommend using Skunk2 titanium retainers and adjustable cam gears.
• DO NOT USE IMPACT GUN TO TORQUE CAM GEAR TO CAMSHAFT. Skunk2 camshafts should be torqued to 22 lbs.-ft.
Skunk2 camshafts are chillcast (iron), with the tensile strength being less than that of factory camshafts (steel). Therefore, the torque specification
for Skunk2 camshafts is less than that of factory camshafts.
• If using an aftermarket cam gear, be sure that the factory cam gear bolt is able to engage 3-4 threads into the body of the camshafts. Thicker camgears
will cause the factory cam gear bolt to only engage the threads in the snout section of the camshaft, increasing the chance of breakage. A
longer bolt may be required when using a thicker cam gear.
Before the removal and installation of parts, please refer to the factory service manual , or equivalent.
These camshaft specifications are the recommended settings. It is the responsibility of the engine builder to check all clearances. For optimum power
the vehicle must be dyno tested and tuned to accommodate for each individual engine setup.
