A: engine blocks in F1 are machined out of Forged Aluminum Billets, not cast. I don't know about the heads. I'm not saying they don't throw a few blocks away, its just they are not cast.
B: the one rule change that would return F1 to a race where passing would take place is effectively prohibited. This rule would ban all aerodynamics and mandate the body have the shape of a convex hull--with some reasonable allowance for cooling ports. No wings, spoilers, barge boards, diffusers, wingletts, fins,... The reason it is prohibited is that these devices are where the majority of the billboard space exists.
C: If you did rule B above, there is no need for rules on engine performance, tires, brakes,... Without downforce, braking distances go up 3X, acceleration distance go up 2.5X, cornering speeds go down 1/2X, and safety improves. At the same time the racing improves.
