I am not sure on the radiator block? Surely the t-stat regulates the temperature and it doesn't really matter how big the radiator is? I will be fitting an upper grill block, the car ran fine during the summer, I just haven't got around to finishing the permanent design yet!
I use FLAMMABLE corrugated cardboard on the cars because as on yours, engine bits-to-hood clearance is almost non-existent. The F150 has the luxury of enough clearance for 1" foil faced foam sheet.

If you can more fully enclose the engine, be my guest. My engine bays all are a potpourri wires, hoses, lines, linkages, hot bits, and sticky-outy parts; to enclose that mess would be quite the project. I think that because heat rises, insulating only the top gives the most benefit and besides, since I haven't "overdone it" the cooling system retains functionality when the vehicle is going, even in the summer. A grille block serves to reduce the breezes that cool the compartment down even further. One caveat: because the F150 is fanless and is called upon to work hard, the grille block comes out in the summer, but the cars stay the same year-around. So it is pretty much a set it and forget it system.
