you might get a kick out of this:
I lose so much power over 5500 that I had to shift at

wait for it.....



6100. It goes slower anywhere else. sooooo this cam has a powerband of 4500-7500, and I peak hp around 5600 with the LS1 intake, think there is a little more in it??

I want to shift around 7100 when I get the intake on it

I shifted mine as high as 7300 but I went slower. Mine liked 6800 it's a matter of shift timing and how far the rpm falls on shifts to really find the sweet spot
