to hood scoop or not to scoop.........

so I picked up a 69-70 factory scoop for cheap and i'm throwing around the idea of using it on my car. I kinda like the way it looks. what do you guys think?

If you like it, I like it. I personally prefer the look of a 65-66 Shelby scoop, even if it's just bolted/riveted on, but that's good too.

I'm really diggin' the harlequin look you have going on with all of those different colors. I'm not sure I could let myself paint that car all one color. Looks cool.

thanks, it's funny, I get asked about when i'm going to paint it every time I have it out. when I first got it together I really wanted to paint it the factory antique bronze (I really like the color), but now the look of the car has grown on me and i'm not sure i'll ever paint it.

I think it's personal preference. If you like it, go for it. If I were to do it, I would make it functional.

As long as you understand that such low hood scoops have absolutely no functionality and are just for looks then it's just what suits you. You like it? Do it.
I came across one of those and tried it on for size on my '67. It looked OK but I have the deluxe hood and decided it looked too crowded. So I hung it on the wall and it stayed there for years until one day most of a '69 followed me home one day and it's now gathering dust on that instead. (Hood even already had the holes.) I'm glad I didn't drill holes in my 67's hood for it. I sure would have felt dumb later.

Is that really true though? I would expect at the very least, a venting effect. Not a very efficient one, but still.

It won't have a ram-air effect, but if the air cleaner fits up into the hole, you'll have cooler air for the carb.

Pretty much. Have you seen the ProStock racer hood scoops that are almost taller than the roof of the car? THOSE work. Anything shorter isn't really in the airstream and functions like a closed dimple in the hood. There's a bunch of wind tunnel type data out there somewhere. It might leak a little air from under the hood if pressures under there are pretty high on your car. Not enough to warrant chopping holes if you ask me. The main function of an open hood scoop is to let water, dirt, and crap, go down all over your engine. If sealed to the air filter you could make a case for the engine drawing in a cooler air charge than it would from underhood but the gains there aren't enough to interest me in hacking a hood either.

Can you open it up? Sure. As long as you don't go around bragging about how much HP you gained by doing so no one will mind.

I'm going to spend +/-$1100 (yea, $1,100) for a "functional" reproduction ram air setup for my 68 firebird 400 hood with the complete understanding that it will do nothing more than look cool. A fool and his money...

Personally, I like it. I think it would look even better when the whole car is painted one color.

I feel a fair amount of hot air come out of there when it's parked, either after driving or sitting there idling. I wouldn't dare say I'm getting some sort of ram air power boost out of the deal, but it does seem like there is a good chance at cooler under hood temps in general.

I have a fiberglass '69 Cougar Eliminator scoop on mine. What I've gleaned:


1) I had to reinforce the scoop underneath with a steel bar encased in fiberglass, as at speed the scoop would "balloon", and it cracked the paint at the front of the scoop . This could also be because I have a crap ton of air coming in through 2 grills in front, and no where for it to go. (See point #3, below.)

2) My air cleaner sits about 3/4" above the hood level, and I have about 1" clearance around the edge. If you cut the hole, be prepared to take a bazillion measurements. It's a royal PITA.
3) If I had my druthers, I would have put it on backwards, like a cowl scoop. Lesson learned lol.

4) I have a foam plug I put in it when it rains. I'm not a fan of wet air cleaners.
5) FWIW, my scoop does help to cool carb air. I can tell the torque difference when I have to plug it up lol.
6) Put some sort of anti-friction foam or tape in between the scoop and your hood (when/if you paint the hood). Foam also keeps water out.
7) Pop the hood to let it cool to prevent damage to the scoop. And yes - lots of heat escapes from that hole in your hood, but it butts up against the scoop on its way out and will warp it.
