I looked at that ford air cleaner setup for the drop base as well. I almost went with it but I'm now going in another direction completely.
Because of my engine build, I was going to use just this:

But I've since sent out my intake to Wilson to have it ported.
I did a lot of sizing with different air cleaner bases but eventually decided to get a new 6-pack bolt on hood form Glasstek (arriving Tuesday next week) as I'm also going to change out my MP valve cover and air cleaner setup.
It may be a tight fit but I have 440 Source fabricated valve covers and will go with this air cleaner:

I want a different look and this has a raised base (similar to the MP a/c).
The 6-pack hood should give me all I need with the carb spacer.
Will get the new valve covers, a/c and any new breathers all powder coated the same satin black.
