I have a 17 Sierra 1500 4x4 with a 5.3 and am looking for cam advice. I have a CAI and a 40 series flowmaster already. I had a local shop do a custom tune and deleted the AFM and removed limiters . She’ll do about 130 with some throttle left and really comes alive at 50-80 MPH. I’m happy of course but want more!! I am going with long tube headers and true dual out the back with cutouts. But I know a cam is where it’s at, but which one???? Aaaaand GO!

Your driveshaft is not made to do anything over about 115. It can and will self destruct. Just an FYI.

There has been a lot of hype on the truck norris cam lately. Something along that or a stage two BTR or TSP. You really dont want all the power coming in at the top of the rpms because you shouldnt be there all the time. You want some down low too.

And you're CAI was a waste of money.
