Once I get my "cowl induction" scoop (note the proper terminology) and bolt it on, where should I cut the holes?
I'm thinking about removing the horn from the stock air cleaner and running 2 90 deg. elbows up through the hood like this:
I'm thinking that keeping the tube above the roof line will help prevent any water from falling into the air cleaner.

73Custom I ordered the chrome trim from LMC, and the body shop that painted my truck had to put the bed on so they went ahead and put them on for me.

Just a follow up.
After looking at all the websites and ebay, I figured I'd take a shot at making my own scoop. I decided on a 4"Hx28"L cowl induction scoop (shoulda went longer though), and I decided to use sheet metal.
I had an old office desk that was scrapyard bound so I took the sheet metal off that. I cut the sides to the profile I wanted, cut the top piece and welded them together. I also used a 1/4" steel rod (driveway marker) welded down the center to create the hump to match the hood. I'll use body filler to fillet the edges and match the hood profile. It also has flanges on the inside, and the bolts that go through the hood are welded to the flange.
The tricky part was making it functional while still using the stock air cleaner. For that I cut two 2"x4" holes around the edge of the air cleaner cover and made some 2x4 tubes. On top of those is a 2" high box with two 3" tubes coming out and through the hood.
Check out My Truck Pix for pix of the scoop. It's not perfect, but what do ya want for nothing.

Are you just going for looks?

neverenough,
That's the part I have to do tonight. I have one of two 4" holes drilled in the hood already. I just have to drill the other. There are two 3.5" pipes that go through the holes so I have roughly a 1/4" gap around each pipe. Hopefully that will be enough.
I'm thinking I'll put a flange on the pipes with a rubber/foam seal to seal it to the bottom of the hood. Or, attach a 1" wide seal around each pipe at the proper level. Id depends on what I can dig up for a seal.
