I was thinking that i would cut the hole in the hood to the correct dimensions, but i want to round off the edges so it wont look unfinished.
Also i dont know how i should go about mounting the scoop. Yea, it would be cool to actually have it engine mounted, but it won't matter from outside. So i was thinking that i would just mount it to the hood. I guess it doesnt really matter since its not a real trans am anyway. But on the other hand i don't want to seem lazy by not building something to mount it to the engine.
I just need opinions on those 2 things really.
1. How to finish the edges on the hole for the scoop
2. Mounting the scoop.
I mounted a shaker scoop to a '81 Camaro hood (had a 455 Pontiac engine in it). I made a cardboard template from a friend's T/A hood opening, then positioned the hole to match up w/the Edelbrock intake and Holley carb. I used a jig saw w/a metal blade, the bracing on the underside of the hood wasn't that hard to cut but it took some finessing to get the bracing cut back away from the hole on the underside so you couldn't see it from above. You'll see what I mean once you get your hole cut.
Anyway, I used push-on trim to finish the cut edge of the hood. There are many
types and styles of this kind of trim- I used some that a buddy had left over. An example is shown below- click on image for info. It actually turned out quite nice looking and solved the problem of rolling/finishing the edges of the steel hood.
As mentioned, there are 305 shaker scoop assemblies- personally I'm not that wild about the style of them, at least as compared to the early scoops that are less angular (which is what I used). And be aware they are all made for a Q-jet carb.
Some scoops can be seen at Hitman's Pontiac Trans Am shaker scoops
In my case, because I only had the scoop w/o the base assembly, I mounted the scoop to the hood (so I had no shaker- but the whole car shook anyway). I used fiberglass to make a piece that was attached to the air cleaner base to seal the filter element to the underside of the hood w/foam rubber so the scoop only pulled in outside air and not the hot underhood air (this set-up used no air cleaner lid). I used a piece of expanded metal mesh to cover the opening.
