Vehicle Group
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
Information
Camshaft (Set of 2).
Restore or upgrade accurate valve-train operation with this OE Match Camshaft Set, reference WC-05-432, supplied as a set of 2 camshafts for compatible engine applications. The camshafts are central components of the valve train, controlling precisely when and how far the intake and exhaust valves open and close throughout each engine cycle.
Fits:
Porsche 911S (74-77) CIS Injection
Size:
#134/149i .465/.450L 304°/284°D
Made of high quality billet blank Web cams have been Race proven for years, and provide reliable HP at all Power ranges.
Special order only
As the camshafts rotate, their carefully profiled lobes act on the corresponding followers, lifters, or other valve-train components. Each cam profile determines important operating characteristics including valve lift, duration, and timing. These characteristics influence how effectively the cylinders fill with the incoming air/fuel charge and how efficiently exhaust gases are expelled.

Special order only
As the camshafts rotate, their carefully profiled lobes act on the corresponding followers, lifters, or other valve-train components. Each cam profile determines important operating characteristics including valve lift, duration, and timing. These characteristics influence how effectively the cylinders fill with the incoming air/fuel charge and how efficiently exhaust gases are expelled.
What This Product Does:
- Includes 2 camshafts for compatible engine applications.
- Controls the opening and closing of the intake and exhaust valves.
- Determines valve timing relative to crankshaft position.
- Controls valve lift through the profile of the camshaft lobes.
- Determines how long the valves remain open through camshaft duration.
- Works with followers or lifters to operate the valve train.
- Helps control efficient cylinder filling.
- Supports effective evacuation of exhaust gases.
- Influences engine torque, power delivery, throttle response, and operating characteristics.
- Helps maintain coordinated valve operation across the engine.
- Replaces worn, damaged, or unsuitable existing camshafts.
- Provides a two-camshaft solution for compatible engine builds.
Symptoms Of Wear Or Failure:
- Ticking, tapping, or abnormal valve-train noises.
- Reduced engine power or acceleration.
- Rough or inconsistent engine operation.
- Misfires or uneven performance between cylinders.
- Reduced valve lift.
- Difficulty maintaining correct valve clearances.
- Repeated changes in valve adjustment.
- Flattened or excessively worn camshaft lobes.
- Pitting, scoring, or other surface damage on the lobes.
- Excessive wear on followers or lifters.
- Metallic particles in the engine oil.
- Abnormal camshaft journal or bearing wear.
- Visible camshaft damage during engine disassembly.
Why Replacement Matters:
- Camshafts directly control valve movement and therefore have a significant influence on engine breathing, combustion, and performance. A worn camshaft lobe may no longer provide the intended valve lift or duration, preventing the corresponding valve from opening correctly.
- Reduced or inconsistent valve movement can restrict airflow into the cylinders or interfere with exhaust gas evacuation. This can contribute to reduced power, poor throttle response, rough running, misfires, and inefficient combustion.
- Camshafts and their followers or lifters also operate as closely matched contact surfaces. A worn or damaged follower can accelerate camshaft lobe wear, while a damaged camshaft can quickly deteriorate the corresponding follower. Metallic particles produced by this wear may circulate through the engine lubrication system and contribute to additional internal damage.
- Because WC-05-432 is supplied as a set of two camshafts, correct installation and synchronisation of both components are essential. Incorrect camshaft timing can significantly affect engine operation and, in applications with limited piston-to-valve clearance, may cause serious internal engine damage.
- Replacing worn or unsuitable components with this OE Match Camshaft Set of 2 – WC-05-432 helps restore accurate valve operation, consistent valve lift and timing, efficient engine breathing, and dependable performance when correctly matched to the intended engine configuration.
