cold air box ideas???
i am entertaining the idea of building a cold air box for my 79...
the original cold air induction was scrapped when i modded my engine bay from stock to "early hot rod"...(bare essentials and color)
i am thinking along the lines of something like Oliver (GrandsportC3)
started...kinda like the NASCAR cup cars use...that induct air from up by the windshield although i wouldnt oppose induction from the front but i think that would be harder to make look good and also take up more engine bay space...
have any of you thought about this too...any ideas???

I like the idea and was comtemplating the same issue. Making a cardboard template and then take it to someone who could weld up one for me. But I don't believe it can be done with a stock hood. I like the Edelbrock Air GAP but don;t like the idea of choking off the carb with a radical drop base air cleaner for two reasons, 1. Sucking in hot air and 2. having the top of the air cleaner so close to the top of the carb. No offense to the peeps that did this, but I wish someone would post some tech data on running a drop base cleaner vs. a non-drop base open element to see if the drop base would offset the gains of the RPM manifold.

im gonna be doing the same thing as you soon on my 73. i am going to try to retrofit the stock air cleaner assenbly with the rubber gasket to my 670 holly street advenger, the stock air cleaner wont fit on a holly without modifaciation to the air cleaner base-the only parts ill need is the rubber gasket. i just got the cowl door operating last fall. now it opens and closes with the gas pedal,(had to buy the wiring loom that goes to the jack by the headlights) i plan on driving the car with the cowl induction and showing it with the chrome air cleaner set up like yours,,,, keep us posted on your progress!--also im not sure if the deck height is different with a stock intake manifold & stock carb,, vs-the elderbrock and 670 holly--

I have a 70 with the dual snorkel setup. It is just begging to get some hoses fitted and then run down to either side of the radiator. I need to put a hole in the radiator support for each side. This will give me cold-air induction. If you have a narrow radiator then the cold air source could be either side of the radiator.
I think you can use the dual snorkels on later model cars if they have QJETS. If nothing else it would give you a starting piece to cut/mod
to add your plumbing for the cold air to come in.You could also check out a junkyard for different air cleaner tops and peice together something. Once you get it right just get it powdercoated and slap on a "keep it all GM" decal and no-one will ever know....

Have been trying to think of a way to make a round one like this:
Was think of trying to extend my my air cleaner base using a wheel shaped piece of alum or sheet metal then glueing a seal like above to it.

Why not just put an L-88 air cleaner box under the hood and duct it from the windshield like you want? Eckler's sells the box that can be 'glassed in to the hood.
I went with an entire L-88 hood, airbox and filter setup on my small block. I have to use 2 inches of spacers to take up all of the extra room so I would expect that it should fit under a stock height hood without problems.

How about a link? http://www.ecklers.com/product.asp?pf%5Fid=10416&dept%
You will have to trim the air-box to mate to the stock hood and as stated above 'glass it in.

I like the L88 hood idea as well. By the way, not directly relevant here but it should get your idea file going...latest Corvette Fever shows the Keisler car (I think it's a '65) with some sort of custom-made cold-air box on it to work with the 350 Ram Jet engine. It's the custom box that is of interest here... Wish they had published better photos of that part of the project... Maybe the Keisler guys will see this thread and give us some...

Here's a pic of my cold air setup that Signguy is talking about. I tested it with a temperature sensor that was routed into the air cleaner. The intake air temperature dropped basically to the outside temperature. In slow traffic, the difference was 30 
degrees and in highway traffic 15 degrees...
That's easy HP..
