Big Block Chevrolet, Gen VI, 1.950″ Journal
Coming Soon!
The Allmond Marine Stage 1 is an evolution of the 168731 cam
The intake event (solid line) is optimized for improved dynamics while keeping the valve events the same. Higher max lift and 1.5° of asymmetry for improved volumetric efficiency with modern cylinder heads
LSA of 113.5° gives equivalent valve events (EVO, EVC, IVC, etc.) to the 168731 cam’s 112° LSA
Adv. Duration | Duration @ 0.050″ | Duration @ 0.200″ | Valve Lift @ 1.74:1 | Lobe Sep Angle | |
Intake | 290 | 227 | 148 | 0.619 | 113.5 |
Exhaust | 296 | 236 | 154 | 0.611 |
