I have a water sucker too. I'd suggest before you go through the effort, do one more check. I'd been driving dirt roads after my v8 conversion and there is a back draft that comes forward on the rear deck to the engine bay. I thought by closing off the grill I could cut down on the dirt.
What I found was LOTS of dirt way up on the aircleaner and manifold. It swirls up from the bottom, having the grill breaks that pressure. I don't have any engine "tin" like the aircooled engines and I do have an airdam up front that may stir stuff up. Just thought it would be a good check for you to try.
I get a lot of dust on the engine cover and deck lid on my v8 even in just a few blocks. Been thinking of building some type belly pan or some other way to get the air out the back of the car rather than up through the engine compartment. I have tried it with and with out the rubber air deflectors and did not see any difference.

Hi Jerry,
When I first did this so many years ago, I'd gone through the effort to make my own engine "tin" for the V8 so it would wrap fairly tight around all the header tubes and fit right into the channel around the engine bay. It didn't seem to make much difference, rather than staying nice shiny aluminum it just got dirty and trapped in a lot of heat from the headers.
I had thought if I were to try the engine tin again, I'd consider doing it above the exhaust. But I'm thinking next time I have the engine out, which may be soon, is to go around the engine bay with a nibbler and take out flange that the tin mated up to allowing greater flow through there.
