&lt;strong&gt;8&lt;/strong&gt;. Crane offers a wide variety of powerful cam profiles for LS applications. To illustrate the difference in displacement, we chose a healthy Crane hydraulic roller profile. The Crane cam offered 0.590 lift, a 224/232-degree duration split and 115-degree LSA. Despite what seems like a mild street profile, this cam allowed the test motors to continue to make power up to (and past) 7,000 rpm.
