Looks great , my mate fitted a compressor from a set of air horns in the engine bay and drilled a hole in the side of the dizzy.
He had some arrangement to lower the pressure,
Everytime he did a water crossing or similar he would hit the toggle switch and pressurize to dizzy so no water would enter.
Never failed him once, I had a similar set up an a HEI dizzy

Always wanted a GQ diesel auto, how do they go??
