Now I have another problem. I've got everything ready to roll in my 75 bronco. I put the holley truck avenger carb on and surprise, the hood will not close due to the high rise aluminum intake. Looks like I need another couple inches or so.
I don't want a new hood, so I was thinking about a scoop.
I would appreciate any suggestions and how-to's as I have no experience at all with body work. I was also wondering how to keep rain out of an open scoop.
Most of the Bronco places sell a hood bubble that is made to rivet to your hood. They come without a hole so you don't have to worry about moisture.
They are pretty easy to install. As they say, measure twice, cut once. You need to figure out where the center of your air cleaner will be. Measure the diameter of the air cleaner and give your self at least an inch on all sides for engine movement and mark your hole. Make sure that the bubble will cover the entire hole before cutting. There are a few different ways to cut the hood. The best way that I have found with minimal damage is a sawzall.
Once you have the hole cut, fit the bubble and trim as needed to match the hoodlines. They come with welting so you don't have to be too perfect. I like to fit it and drill and rivet one hole in the front. And then I re check the fit and drill and rivet on one side. Work around it and make sure that it doesn't bulge up.
You can also have a custom scoop grafted to your hood for a cleaner look. But, that is something best left to a body shop that specializes in fiberglass work.
freind of mine has 76 bronco,he put a 351w in it,had same problems with the hood,he brought it to my garage,we "made" a nice shaker scoop for it,with weather seals around it,looks like factory made,if ya have someone with a little knowledge of sheetmetal fabrication,its not hard at all & looks real nice & plus,you have no bondo in the hood which could be a problem later on from flex
On one of the broncos I built I found a factory scoop in a junk yard off, I believe it was a Torino. It had factory turn signal indicators in the back and was only about two and a half inches high. I only had to cut a circle out of the hood a little larger than the filter and then the scoop had maybe six studs sticking out of the bottom that I had to drill for. Simple installation and a good looking scoop from FORD!
The last time we needed a scoop we took it off of the 84 donar mustang GT we had been parting on. It works well as it is pretty flat on the bottom and has six hold down bolts. good luck
