Looks like x-mas came early this year. My wife and I just went to Loper's Performance and got my new cam, springs, lifters, retainers, valve locks, push rods, and roller rockers. Everything is from COMP cams. The grind number for the cam is G3 XFI261 HR15. 208 212 .554 .558. The rockers are a 1.75 rollers. I have a 05 silverado with LT headers w/ no cats, single 3'' flowmaster super 44 exhaust, CAI, throttlebody spacer, MSD wires, and a custom tune. I am looking for some opinons if this is a good set up or not.
