Camshafts are the most critical part in determining you engine's performance. Designers use a combination of separation angles, lift, duration and lobe acceleration (ramp rates) to create a unique cam profile to suit a selected performance window. Which profile you choose will determine where in the curve maximum horsepower and torque will occur ... so selection of the correct camshaft is critical. Optimizing the cam profile also depends on matching the valve events to your cylinder head and valve train components capabilities.
