Camshaft Duration Calculator
Calculate cam timing events and overlap.
Cam Profile Guidelines
| Application | Duration @.050" | LSA |
|---|---|---|
| Stock/Mild | 190-210° | 112-116° |
| Street Performance | 210-230° | 110-114° |
| Street/Strip | 230-250° | 108-112° |
| Race | 250-270° | 106-110° |
| All-Out Race | 270°+ | 104-108° |
LSA Effects
- Wider LSA (112-116°) - Smoother idle, better vacuum, emissions friendly
- Tighter LSA (106-110°) - More overlap, lopey idle, peaky power
- Advancing cam - More low-end torque, earlier powerband
- Retarding cam - More top-end power, later powerband
