Cowl Scoop
 

I am intersted in purchasing and installing a metal cowl scoop from The Speed Center. The installation looks pretty straight forward. My concern lies with the need to trim the rear of the unit. The scoop is 53" long and the hood on my 72 is approximately 44" from rear lip to front roll. Have any of you used this unit and have any advice?
Thanks,
Larry

after you put all the work and money into this project i think you would be better off to just buy a cowl hood. good luck

Orence1-
Is the truck in your avitar yours? If so, post some more pics. I am leaning toward a black truck and would like to see some more. Where is Bothel, WA at. I am about 6hrs from Spokane.

I've actually been thinking I may do a ram air hood, simliar to an early 70's Firechicken.

Re: Cowl Scoop
 

The choice of a cowl scoop vs a new cowl hood came down to two factors:
Money- The hoods are nearly $400 not including shipping. The scoop is $175 with shipping.
Fit - My current hood is in excellent condition and fits perfectly. I know that at times new sheetmetal can be a pain to fit properly. One of the options they offer is an epoxy adhesive that will attach the scoop rather than welding. Being somewhat concerned about warping I did some research on metal adhesives. I am pretty confident that the adhesive will work well and negates the risk of heat damage. I'll post some pictures when done. Thanks for the replies.

Awesome, I look forward to seeing your results.

do you have a link to the scoop you are ordering?

Re: Cowl Scoop
 

Orence1- are you planning to just glue it to the top or cutout a hole and mount from underneath?. I had a fiberglass scoop riveted and smoothed into my last truck and it didn't last long. It looked great for 3 months. The problem was the body filler started to crack where it was feathered into the existing hood. This was due to vibration and closing the hood. Maybe if you can weld the edge somehow and grind it down to minimize filler it would last. My buddy did his GTO 5 years ago and it still looks good. Good luck.

Re: Cowl Scoop
 

the hood flexes so much, anything bonded to it will crack unless it's metal on metal, or fiberglass on fiberglass.

Crazy,
Thanks for posting the URL. That is the company I am planning on purchasing from. You guys are right on with concerns about cracking. My original thought was to do a fiberglass scoop as they are fairly inexpensive. After some research however, I discovered exactly what you described. Lots of problems with cracks. It appears that the lip will need minimal filler to blend it to the hood and the tech at The Speed Center indicates that they have not had reports of cracks. I am planning on painting this summer so will install the scoop and keep the hood in primer and check for cracks before the paint process. Will keep you informed. Happy New Year.

I am no bodyman, just a good old backyard "jack". I have done a little tin work, & do agree with the majority.....that hood will be a PITA to weld a scoop on, or glue & fill! My thoughts are , that if you can cut the hood to pull the scoop up from the BOTTOM side,& button weld it to the hood. then add a little good paintable seam sealer, rather than filler.....it may hold up better. I havent tryed this, so bear in mind that it is just a crazy thought, from a crazy old man;) :crazy: L

Here’s an idea I just thought of:
Fiberglass scoop with a 1/2" - 1" lip that is hidden underneath it that runs front to back, and across the front. Drill holes in that lip, and in the hood, and rivet it on. Drill a drain hole in the hood behind the front of the scoop for a water drain, and you can get fancy with that so water drains out somewhere else other than your engine if you want. Then if you want it water proof, seal the base with silicon, seam sealer, or gasket material. If you want it functional, cut the hood and the rear of the scoop.

That’s just how I would do it if I didn’t want any bonding material to crack. Just don’t bond it in other words.

i molded a 3" cowl scoop on my hood put alot of time into it then found out later i had to trim about an 1" off the back cause it hit the cowl panel when it opened. but still was well worth it cause i didnt have to spend $699 for the hood. all those hoods i seen in person, they dont line up good. i figured it be good to just mold one on cause i know the hood already fits and lines up good. later...

Shane,
Thanks for the offer. Do you get anywhere near Kent during the week? Have a board friend that lives there and we swap labor often.

Re: Cowl Scoop
 

A buddy used one from them on a '64 Impala. Looked great and his body guy done a excellant job. I thought he got a cowl hood. I agee cheaper than a hood. Try it!!!

Re: Cowl Scoop
 

i was in kent today...but im always in my work van if im up there so the hood wouldnt be with me...

Re: Cowl Scoop
 

ebay truck, example of cracking body filler. i can go down and take pics of my friends 4th gen camaro with "ram air" cracking too if i felt like it.

Re: Cowl Scoop
 

I would use the metal adhesive but how would you go about fitting the scoop to the hoods body line???

Re: Cowl Scoop
 

heres a quick shot of my hood. pic quality sucks but ya get the idea. and as i stated above i had to cut some of the back off. and for the body line i just blended it together on the edge in the front. i wish i had a better pic so its more visible but it looks great.

Tom,
Can you provide a bit more detail on how you formed the scoops center "raised rib" to match the same rib on the hood? I have some ideas on what I was going to do and would be interested in how you matched yours up. Looks great by the way. My thought on the metal scoop was to cut a notch on the front lip to match the hood line and weld the notch edges. Thanks for the input.
