I'm thinking of getting a fiberglass cowl induction hood.
Does anyone have a good supplier they like?
Thanks, David

Just a thought,

Dont you need to remove the hood hinges and have a lift off hood when you use these things, I have heard that they dont line up correctly so you cant use hood hinges...

Maybe I am retarded today , but I thought I read that somewhere.

I bought an L-88 hood from Motion Performance. It is a very nice piece. No warping and good exterior finish. Minor issue I had was the underside is pretty rough.

My hood is the "street" version so it is a little heavier that the race version. It has bolt hole provisions for the hinges and front latch. I also bought a set of light weight springs so I didn't have to use a prop rod.

I don't know if they make cowl hoods or not, but it might be worth a call. They advertise in the back of Hot Rod and Super Chevy, don't have the number handy.

Not sure who makes them, but I saw one at a recent show that used the stock hinges. You have to pin the front, couldn't mount the stock hood release mechanism. Maybe someone else can provide more info, but I know they are out there.

Is this for a race car or as a substitute for a steel one. A long time ago I picked up a Harwood fibergalss one but it had to be pinned in all four corners. The pins take away from the factory look but it weighed something like three lbs

There's a company I think in FL that has a hood on Ebay for $199 constantly. I think it uses stock hinges and pins up front. I also saw some for sale on traderonline.com in the bargain trader area.

I have a steel cowl hood now and it weighs a ton. I'm thinking of a street type that uses the stock hinges. I really don't like hood pins but may have to use them if required.

I also have a stock hood that someone cut a hole in the center. I could use that and install a cowl hood scoop on it. I don't know what the weight difference would be between that and a complete glass cowl induction hood.
With that, I'd be able to use the stock RS hood latch and avoid the hood pins. The only problem with that is doing the fiberglassing of the scoop.
Thanks, David

A friend of mine just bought one from Harwood (about $400). Its the bolt on one, it has a very nice finish top and bottom. Needs minor triming on outside edges (not much). You remove or install low tension springs, and it uses stock location for latch. They have a pin on version also so make sure to say bolt on. I think you can get it through summit, or from Harwood.

I believe Steitlow put a Harwood on his Thrasher. From the pictures, they use the stock latch and the fit looks good. I also have a steel cowl hood. I had an SS hood with the heavier springs, according to GM. I put the lighter springs on although I must say the cowl hood did not feel lighter than the SS although I've read that is the case.

Thanks for all the info guys.
Does anyone know what the harwood bolt on hood weighs? I'll probably call them.

I'm going to weigh my steel cowl hood and compare.
I'll post the weight here.
I'm not going to do it unless there is a significant difference.

Go for all the fiberglass from UNLIMITED PRODUCTS, lots of 67-69 camaro Glass, lexan, etc... www.up22.com (http://www.up22.com) great fiberglass for all kinds of cars and the accesories for the parts check'em out good prices !! I might get fiberglass quarter panels from them. Lighter, strong, and lest costly..... http://www.camaros.net/forum/biggrin.gif

I have a 4" cowl hood from unlimited. The steel inserts aren't exactly in the right places, buy was able to modify the hinges to fit. It does fit pretty good but not perfect. The gel coat was a little uneven, but some sanding and sanding primer fixed it. I think Unlimiteds cowl design and length matches the factory design the best of all the fiberglass hoods i've seen. I use the light springs on the hinges and the mr. gasket locks with the round key. This hood is not flimsey and is about 1/3 the weight of the SS hood I had. I can easily take it off and install it myself without damage. You can kind of see it in my website on the blue car.

Lonnie67,
You have some very nice cars!
How does the 4" hood compare to a stock height cowl hood? I mean when you are driving it, does the hood seem much higher?
I would like to go with a little higher hood. But if it interferes with visibility from the drivers point of view it might be a problem when autocrossing the car.
I've got a downdraft Weber carb setup I'd love to try in the car but it's 12" tall from the manifold front oil seal to the top of the carbs and I don't think it would fit under a stock cowl hood.
Thanks again, I'm getting good info here.

Thanks for the compliment David.

I just went out and measured both hoods. From the cowl vents to the flat part of cowl hood it measures 3.5", 4" must be to the peak in the center. 1.25" taller than the stock type cowl on my red car.

IMO it looks really good, not too tall and not gaudy in the least, like some of the other tall cowls i've seen. There is no mistaking that it looks taller from the outside and inside the car.

I really don't notice it blocking my vision from anything, but I have never autocrossed.

I have the tall solid motor mounts, a Team G, 1" air cleaner spacer and a 4" air filter and I still have a few inches of clearance. I recommend it.

I just read your post again. I have 13.5" of clearance from the front manifold seal to the hood where the front of a 14" air cleaner would hit, and I have 1/2" taller motor mounts.

According to my measurments, your set up should clear the stock cowl hood.

Okay, one more,

Just looked at Unlimiteds site. It's the 3.5 cowl hood I have. Part #CA139.

From what I've heard Harwood and Glasstek make the highest quaility hoods. This question comes up quite often on the NSCA bb, and most say that Glasstek is the better of the two, and Unlimited is not even in the same ballpark. I know Harwood makes a bolt on type to be used with lighter weight springs but I'm not sure about Glasstek. Here is Glasstek's number (630) 978-9897 .

i got this web site from a fellow board member. they were the only ones that carry the 67 vette stinger type hood for the camaro at a reasonable price - still haven't got one yet. they have a large selection, so you may check with them.
http://www.vfnfiberglass.com/
in checking on hoods, i think most have 3 different styles: use weaker hinges with front pins, use stock hinges with front pins and prop req'd or use stock hinges and stock front latch with no pins req'd.

If you go to a lighter fiberglass hood I would think and every one that I have seen use weeker springs, if not when you popped the latch it would fly open.

Lonnie67,
Thanks for the measurements.

Does the unlimited glass hood have a round air cleaner hole in the center underneath like the origonal cowl hood?
I guess I'd have to cut it out to make the glass hood clear the webers. And maybe I could make a seal to seal the carbs to the hood.
I don't want to cut up my steel cowl hood. It's an origonal from GM parts, bought years ago. I paid $75.00!

Mark,
I'll have to get the soft hood springs or it will warp the hood up just ahead of the springs in addition to other problems.

I may start out with the steel hood and a single four barrel til the body work is done. Then I have a offy crossram to try and the webers. I'll stick with whatever works best.

I have a crazy idea to try to make a fuel injection out of the crossram. Replace the carbs with throttle bodies. I don't think there is a good place for the injectors though. They might fit down the center of the manifold going into the center of each port. If placed in the port just going into the head two injectors on each side would be right under each throttle body. not too good for air flow.

The Unlimited hood is fully open underneath.

Thanks again guys.
Mark,
Larry's engine is super!
Thanks for the links.
Those carb body assemblies should fit my weber downdraft manifold and might be shorter too.
