I'm sure this is overkill for what you're looking for, but it is "original", used on CSX3015 & CSX3303, the twin paxton 427s belonging to Carroll & Bill Cosby:

Hyde, is that a paint roller tray?
'lakester, 14" drop base aircleaners can be good in situations like yours. You can have alot of drop and still have good flow, the linkage arm will probably determine how low you can go (limbo music). I used to use one, the raised center section fit within the scoop but the outer edge was just too big to fit within the scoop and would nearly touch the edges, it was tempting to modify the outer edges by squashing them inward a bit. There are also some offset bases available: http://www.pitstopusa.com/detail.aspx?ID=55371

You go mounting that hood on your car & you open the hood to w/o twin paxtons there are bound to be a few dissapionted guests It is a very intimidating look though

Morris, when you look at your picture in your gallery, below it is the address of that pic so that you can copy and paste it, there's even a little "copy to clipboard" button to simplify it. That way you can have large pics in a post without the size limit. Here's a pasting of the address of one of the pics in your gallery:
It looks good! Are you goint to do anything special on the inside?

Mike

We have opened up the hood to accomodate the 16" air cleaner and will mount some side vents into the place marked in the photo....

And yes we'll build a box to get the air into the carb.....

Thanks for the photo info.....we'll try it....

Yes we will have to make a box for the Dominator and hood .....

And we need the 16" air cleaner for the Dominator..... didn't want to compromise the motor....

Y'know..., the funny thing about the "Paxton Scoop"..., I actually kinda like it.

No nasty discontinuity..., the whole hood is a scoop.

But I agree w/ *13*..., if there weren't any Paxtons underneath..., people might be disappointed.

Saaaayyy..., there's an idea!

Iv'e seen a similar scoop on a car from Daryl Holiday in Huntsvile Texas. Actually it looked as if it were planed and not as a ( try this ). The hole under doesn't have to be as large as the scoop and it would keep out a lot of rain on the distributor. The twin turbo scoop opening sets forward and looks like it would catch air being pushed upward by the front end. I was told that the original scoops quit at speed because the higher presure air rolls up over the car and doesn't come back down untill the wndsheild. Probably picks up more air at speed than the original small scoop setting further back. I'd be in the market for one if someone made a scoop like that.

Some thing I have never understood and need some help with....with a cowl induction hood how does air go in if the high air pressure keeps the air off the hood until the windshield? It seems logical that the air would follow the angle of the windhield and continue over it, not into the cowl induction hole. In addition, wind forced through the front would need some place to go and with higher speeds, it seems the air would vent out through the rear opening while crossing the carbs with warm air. Where does my logic (or lack of) go wrong?

As I understand it the air flow would varry as speed changed up tp a point. At highway speeds the air goes upward leaveing the nose and returning to tumble at the windsheild creating a high pressure area. Watch NASCAR, they use cowl induction. An entance farther forward on the nose would work better up to a point . My question is just how much forced air is there. I can see cooler outside air up and out of a lot of the dirt at the road surface. But with varring flow would a flow though scoop take advantage of both nose flow and then cowl when it started to take affect. Also a seal seperating warmer air from the radiator and around engine. I have seen foam sealed plates and prestine sheet metal that fit from wheel well to wheel well arund the engine above the exhaust manifolds .A real work of art.

Yetiman, I have to second Proudlakester's opinion of the 1st photo. Is that what all the fashionable big feet are wedding now days?

Proudlakester, I just used a mock up engine with my tunnelwedge hi riser manifold and carbs to see if its all gonna fit. I think my engine sits forward of yours by about 2 "more than yours, I could be wrong, I'll have new photos up on my blog this weekend. Michael

Here's how the Hood scoop ended up mounting to the hood along with the Vents...

Because of the angle of the Windshield....

The air will hit it and go up and down..... the air that is going down is a very high pressure and is then forced into the rear opening of the hood scoop....

Try towing your car on an open trailer with a light weight plastic bag taped around the body..... you will see exactly where all of the air goes....

Any air pressure under the hood will evacuate out the vents.... along with the heat

Looks like a work of art, post a finished shot of it on the car. Thank you for the info re. where the air goes. *13*, I'll check my history books re. the 60's, is that under Beatles? Thanks Morris

Smile Maybe this helps

Hello Lakester,
Wow, what a small world. I have owned a Bennett cobra for 13 years and had to fabricated a custom air cleaner. There are only a few Bennnett cars out there but Paul made a nice chassis!!

The engines are set back from the front axle centerline almost 24" so the carb almost ends up at the hood brace like your photo shows.. I have photos I can email to you if you would like. My photo software will not compress them enough to post on this site.

From aluminum sheet I fabricated a low profile rectangle shaped air cleaner and installed two layers of Uni air filter foam. It just fits under the hood and I have the standard cobra hood scoop.

Regards,
Jeff
Modesto, Ca
