More drastic in what way? What force on the chassis is being magnified by such a change in geometry? What does that mean for different circumstances on the track? I'm not arguing against you, but you are making blanket statements that are easily mis-interpreted. Technically the car is .003 inches wider with the 2.5 block, the arm becomes more trailing by half a degree, and without adjusting shims increases the wheelbase by .05 inches.
