I am struggling with how much to shave on mine (wire harness guides are already gone). Part of me wants to shave everything/relocate ports to the rear...but then I have to do something with the ugly fuel rails and crossover. Yours looks like how the factory SHOULD have done it.

It is welded. but not sanded smooth. I need to take it over to dad's house for that.

What did you do about the EGR hole and the purge solenoid hole? Did you weld those up too?

They say that their is. I'm not sure that I'm convinced yet.
I see that their could be potential for more air flow with it's larger TB but if the air flow isn't needed for the particular engine, then their'd be no power gains.
People have made plenty of power with a 78mm TB. Guess it all depends on your engines power goals.

I'm not sure this would actually be testable. Correct me if I'm wrong, but aren't gen3's cathedral port heads and gen4's rectangular port? So the two intakes wouldn't even be matched up correctly to the head if you wanted to do a back to back test.

I just realized that I've never looked at a truck intake that came with 6.2L L92 heads square port heads yet.
