ok, here's some pic.s of my under hood. First I determined where I needed to cut the hole in my donor hood, as it was critical, as I have an air grabber aircleaner ( oval ) and it's quite large, and I need the clearance because it protrudes up into the opening because of the M-1 intake I have. As you can see, the hole I cut, is basicly the same size as the bottom of the six pack scoop. Then I made a metal brace, as once the hood skin, and the bracing is cut away, the hood becomes somewhat flimsly, and if you do not brace it somehow, the bondo will eventually crack around the scoop. ( I'v seen it happen a lot!) You can see that I made the brace ( it's just folded sheet metal, and I rolled the edges for strength) so that I welded it back into the factory hood brace and this made the hood nice and rigid again. Then I drilled and bolted ( YES definitly bolt or rivit your scoop, even if others here say it's not nessessary) the scoop, also using a bonding adheasve between the two, and let it setup for a day. I have seen scoops come un-bonded from hoods from a quarter mile pass, down the drag strip, so I stress to you to use a mechanical fastener as well as bonding your scoop !! This next step is optional, as some folks just mount the scoop and call it done, but I prefer a more finished look, as I like it to look like part of the hood, not just somthing plunked on the hood. Anyway, after the bonding adheaseve as set-up, you can rough up the sides of the scoop with some 36 grit paper, and the hood area around the scoop as well ( I sanded the entire hood down to steel, and epoxy primed) and lay a few layers of fibeglass ( matte and resin) around the entire scoop, and let dry. Then I came back the next day, and roughed up the new fiberglass a little, and spread a couple layers of body filler on top of that and sanded it to shape to blend the scoop into the hood. Thats pretty much it, and then of course I painted the hood organasol to match the rest of my car. I also sprayed the under side of my hood with a spray in bed liner material, and this seals out any moisture from getting into and seems, etc. I hope this gives you some insight, and answered your questions. Give it a try, take your time and have fun !!
