I wouldn’t personally spin that sbe to 7k, but that’s just me. And like others have mentioned, the tbss intake is the best bang for your buck. If you want to move the power upstairs, change the cam. Spinning the motor faster won’t necessarily put the power “higher” where you want it, if anything the power will fall off regardless of intake choice. Camshaft dictates a lot of where an engines power band will be

That's a pretty small cam for a 6.2, what is the suggested powerband? I think a larger cam will carry the power further into the RPM range.

That's a very driveable cam for a street driven truck. With the 2800 stall, street comfort seems to be a priority over max effort which I'm totally on board with. I don't see much room for NA improvement based on his mods and how it's driven. Next step is forced induction.

I agree, it is nice cam for daily driver. If he has plenty of low end grunt, and wants more on the top, a larger cam will help. I think it would be a pretty substantial NA improvement.

Or of course, forced induction :-)
