I advised comp that the heads were stock, and the truck is daily driven with very little track time. Thats what they recommended.....
I imagine that quite a bit of testing was done on the cam. When you put the part # on the comp cam website and it opens up this particular cam. It says "LSR™, 265LR HR12
Very Strong Torque & Excellent Response" also "LSR™ Cathedral Port (Small Displacement or Max Torque, 4.8L-5.3L)" and "HYDRAULIC ROLLER-Very strong torque and excellent response. Works best in heavy vehicles, low rpm applications."
