Clevite Performer Hydraulic Camshafts- 'mild' Performance

Good torque, performance gains in the low and mid range. Good idle. Can give power to 5500rpm
Important: Check that your valve springs are not ”coil binding” at full lift. It should be possible to open the valve a further .090”, at full lift, with the lifters full of oil, before the spring becomes ”coilbound” or solid. Alternatively, use the valve springs listed for the cam, and install them at the correct height.
