11 For our first adventure with Modern Mouse, we chose a mild cam profile. The XFI RPM cam from Comp Cams offered a 0.522/0.529 lift split, a 212/218 duration split, and a wide 114-degree lobe separation angle. Equipped with this cam, the idle vacuum dropped by less than 2 inches while the power output jumped to 385 hp and 412 lb-ft of torque. The mild street cam improved the power output through the entire rev range.
