Do you know the cam specs? My 6.0 running flat tops and a 224r TSP cam on 112 lsa got 360 rwhp but I could only get 11mpg. I think the 112 lsa and the 3200 stall converter killed the mileage. My 5.3 got 18mpg in town with stock stall and stock LS1 cam. Small part of the reason I’m going back to the 5.3, adding a turbo, and switching to a 4l80. Hoping to get the power AND the mileage. Also, loved the cam lope but didn’t like the truck shaking at every stoplight.
