Custom Hood
Custom Hood
I found a fiberglass hood for $50, so in my quest to have something different on my 3rd gen, I am going to use that hood to fab up something other then the usual cowl or ram on the market now. One of my ideas is something like the old duster scoops. What are some opinions on that style on our cars? Anyone want to share some of their ideas?

Re: Custom Hood
Is this for a Camaro or Firebird? and what design fiberglass hood is it now? have pics to post?
Re: Custom Hood
Its for a camaro. It is a Z28 hood with the louvers. My plan is to glass the louver area and then fab something up. I was thinking something along the lines of the old flat hood scoop style. Since it is my daily driver, I want to be able to close the openings whenever need be. I am thinking of something like a servo or small motor attached to a plate that will block off or at least limit water coming in through there. No pics yet, I am still in the middle of the ocean, but soon as I get back on land, I will get some. Hopefully I can have something made for a mock up aswell.

Re: Custom Hood
I've picked up a lot of the factory fiberglass hoods over the years to experiment with them.
My first hood had an aeroscoop mounted on it. It took a lot of fiberglass and bondo to fill in the louver area in front of the scoop. The hood was heavy.
Second hood I tried some sort of modifications and wound up scrapping the hood.
Third hood had most of the middle removed and had a 6" cowl installed. The cowl was long enough to completely cover the louver indents in the hood.
Switched to a tunnel ram and cut a hole in the top of the 6" cowl for the filters to poke through.
Last year I finally took the 6" cowl off when I changed tunnel rams and switched from carburated to alcohol injected. I attached a 2-1/2" cowl scoop onto the hood which was still long enough to cover the louver indents. I cut a real nice hole in the top for the toilets to poke through but since I don't have filters for them, decided to put a short 4-1/2" aeroscoop on top of the cowl.
Looks great but catches a lot of air at 130+ mph. It starts around the 1/8 mile mark and lifts the cowl about 2" as I cross the finish line. I can remove and run without the aeroscoop but I like the look of it on.
Fiberglassing over the louvers is a lot of work and adds a lot of weight. To install a small scoop like one from a Dodge or Ford, you're better off buying an aftermarket fiberglass flat hood. I wish the factory fiberglass hood was flat.
I've always wondered how hard it would be to make an aluminum hood? Third gen hoods are very long and wide. It would have to be made in 2 pieces and joined down the center.

Re: Custom Hood
I have seen the pictures of you car on here from time to time, and I must say, I do like the hood. However, for what I have, I do not think that having a aeroscoop would make much sense, at least not until I get the funds to get my weiand 6-71. I didnt think that filling in the louvers would add that much weight. Hmph. I wonder how doing something like making a small recess lip around the louver area, putting a piece of thin sheet metal and then glassing over that would work?

Re: Custom Hood
I always thought the early second gen formula firebird twin scoops would look cool on our cars. Just a thought...
BTW, I have the crossfire Z28 fiberglass hood sans functioning flaps. Cost me $35 from a wrecking yard.
