Holden V8 304 355 5.0L VN-VT Carb Hyd Roller Camshaft 242/246@50

Holden V8 VN-VT Hydraulic Roller Camshaft – 304/355/5.0L, 242/246 @.050" (41725)

Designed specifically for the Holden V8 304/355/5.0L engine family in VN-VT applications with carbureted VN heads, this hydraulic roller cam delivers a potent mid-to-upper RPM punch with an intentionally aggressive feel. If you’re chasing a noticeable uptick in throttle response and sustained top-end pull, this cam is engineered to move your build well into the 3500–6800 RPM range.

• Part number: 41725
• Engine compatibility: Holden V8 304/355/5.0L, VN-VT, carbureted (carb VN-VT heads only)
• Cam type: Hydraulic roller
• RPM range: 3500–6800
• Duration (advertised): 306° intake / 309° exhaust
• Duration (@.050" with standard setup): 242° intake / 246° exhaust
• Lobe separation angle: 109°
• Lash (hot): 0.623" intake, 0.623" exhaust
• Notes on fitment and requirements: Machining required to fit these components. Must use performance springs and retainers. Must use a performance seal. Requires proper setup beyond the cam itself for reliable operation.
• Recommended enhancement path: For best results, pair with performance heads, intake manifold, and headers, and consider a higher-stall torque converter to maximize the RPM range and throttle response.

Performance and drivability are optimized when the engine is paired with a complete upgrade path that supports the hydraulic roller design. The cam’s characteristics translate to a lively idle and a strong pull through the mid-to-upper RPM range, making it well-suited for enthusiasts who want responsive throttle feel and confident acceleration in VN-VT builds.
