how to attach fiberglass scoop to steel hood

[Matt167]

I have no hood clearence for my carb, so I gotta make room for it, so I bought a fiberglass reverse teardrop from speedway, but I don't know how to cut the hole for it or anything, what do I do?

Mark where it will go on the hood, cut the opening you need for clearance and attach the scoop. Bolt the scoop to the hood, make sure you use flat washers on the fiberglass scoop. Don't try to glass or mold it to the hood. Fiberglass and steel expand and contract at far different rates and it will crack.

Make a template of the scoop mounting flange and position it on the hood. Move it around the hood for the best clearance and eye appeal. Use this template to mark the location for the mounting holes on the hood and the scoop mounting flange.

Here's a somewhat related story, since it involves cutting a hole in to a car.

A long time ago in a local auto parts chain store that died off around the time that the autozones showed up, I was working on Saturday morning. In walks a couple drunk guys (this is at about 9am) and they ask if we sell sunroofs. I show them the different ones we have and I ask what kind of car they are going to put it in. It was some big boat of a Pontiac so I suggested they go with the largest one. They buy it and drive away.

A couple hours later they show back up, in the previously mentioned Pontiac the size of a house and if anything, they were even more drunk than before. It's easy to see that there is a big hole in the roof of the car. They are both laughing and ask if we have a larger sunroof than the one they bought. I tell them no, and they ask us to come outside and look at something. One of them gets in the car and the other stands outside of it. The guy inside lifts up the sunroof we sold them and it passes right through the hole they cut.

Near as I can figure, they laid the sunroof on top of the car, traced a line around it and started cutting...

haha, Matt, you can put a sunroof on the hood!

well I might just buy a fiberglass hood for $349, then cut and glass in my reverse teardrop. mine has the lip on the outside and not on the inside, so bolting it on would look doofy. had I known, dearborn classics has 1 with the lip in the inside of the scoop so the bolts would be invisable, for $120, but I arleady got this speedway 1 also, probably going to get 2 fiberglass front fenders, mine are rusted at the bottom, and fiberglass is the only reproduction replacement, and it's lighter.

[pat mccarthy]

did you read what i posted? you cut the lip off the outside. glue a wooden frame you make and glue the in side of the scoop with mar glass ?

[Matt167]

I did, but I guess I didn't understand what you meant. I understand now. just might work.

well i did drag car hoods like this and run over 130 + at the track they did not fly off so it works just up to you and how well you do the job. i would paint the scoop off the hood and then all paint was dry i lay a small bead of clear silicon down before to the inside of the scoop and hood . i screwed it down wipe up and done
