13. The final test was to install a custom cam from Comp Cams. The hydraulic roller profile offered .587 lift, a 239/247 duration split and a 114 degree LSA. Certainly hotter than the 260H-13 cam, the stroker responded with peak numbers of 526 hp and 451 lb-ft of torque. Both the SRT8 and truck manifolds were run with this wilder cam and though the power curves varied slightly through the rev range, the peak numbers were nearly identical.
