Yes sir,
Stock truck intake doent have a provision for vacuum port's. The car lt1 has a port iirc. But no need to buy it if the vacuum pump fits between the frame rails without mods so why not keep it for the brake booster and in the trucks application vacuum ac controls. Expecially for the guys that do cams. There's hydropower option, but again more parts to buy. No worry about lack of vacuum with either option. To me, be silly to delete the vacuum pump only to by a electric vacuum pump or retrofit hydroboost. The way the intake is molded... it seems someone would have to cut into it to make sure they get the right spot to get the vacuum source.
As far as DOD... im sure most people swapped or not remove that feature.
But the beat thing about swaps is the aftermarket support
