But with electronic control and little designing you could make valves be open too, if there is clearance. There is also solenoid route too from my memory, really long time since I looked into these, but everything is really old stuff.
I don't know how exactly it is done in 300C SRT8, but there is fuel saver mode that squirts fuel for only some cylinders, it is running then with only 4 cylinders.
There are many possibilities these days, they might be bit too expensive to pay back during lifetime of car, but world needs pioneers, right?
With big motor there is always issue of it needing more fuel than smaller engine, to get better economy motor need to be 'made smaller' to get past that minimum consumption motor has and with such large engine as Crown Vic, minimum might be rather large, getting rpm too low will increase fuel consumption from my understanding as torque curve will drop some point quite fast.
