I wonder if it would be worthwhile to make a lower manifold to mount a Cobra blower on? They are fairly cheap to get and it seems like there could be enough room to mount a special lower manifold with intercooler on top of the pushrod motor.
It would be kinda cool to have that Cobra blower whine on top of a 5.0 engine, I'm almost tempted to buy a blower, and use it along with a stock lower to model something up in Solidworks and see if it's doable.
