Yes, I agree. The best thing to do to a 5.3 or 6.0 is to add a cam. That can give as much as a 50hp gain.I would love to have a 6.0 and 4l80e. My burb is a 4wd rolling on 35 in tall tires. I am actually looking for. The fuel economy along with power, with that being said for the right price i might be persuaded on selling my 5.3/4l60e combo, so I can get a 6.0/4l80e.
I have a harness and ecu from psi conversions, programmed for 2 fans. And the Dirty dingo mounts are definitely the way to go. The burb already has a tranny cooler. The 5.3/4l60e was going into a Yukon, but had too many vehicles, my development says.[emoji852]
