Era fia fast efi 8 stack project...

That's pretty slick! My plan is to build a box out of aluminum that would attach to the hood and scoop encasing a filter element. It would then seal against the stacks with foam when the hood is locked into place. It might end up being pretty restrictive at WOT but I think the computer will compensate and the filter box will only be for street use and the car does not see WOT very much on the street. The filter box will be removable for track use. The magic of Velcro!

The answer to alignment issues may be make something similar to my base that has a flange that seals to the hood mounted air box. You can lay a layer of stretchy saran wrap or similar over your 8 stack set up, then glass it. Once cured, just lift if off the 8 stack and reinforce or add a flat flange.

I've made many small fiberglass parts like that.

I can see it being a challenge to line up a box with 8 holes on the hood. Having 2 boxes, one with filter and one that just seals to scoop would be cool, and easily swapped.

Now you have me thinking fiberglass would be a great way to go.

Considering you have an ERA with pretty a close to traditional theme, I see where you would want to make it out of aluminum. But you can make some pretty nice looking and functional parts from 'glass.

Here's what I did with my Cobra. I have a 427W with port injection and 4 bbl throttle body. I made a 'glass turkey pan that uses the oval Cobra air cleaner and lid, but my base.

It was a 2 step process that you could use for your set up. I made foam plug that had high sides, but the base was carved for room for throttle linkage and various other bulges. Glassed it, then through the vent holes, marked, trimmed, marked and trimmed so I have a nice 5/8" clearance between the edge and hood.

Next, I masking taped the bottom of the hood and drew where the base would hit if it did touch as well as 4 or so witness marks. Then I removed the hood, layed the base on it and put a couple of hot glue dots to hold it in place. Because of the back reinforcing rib on the lone star hood, I slid the base back 1/2". This made it so the actual finished scoop would be shifted forward giving ample clearance. Next glass the flange. After a bit of filling and loving with sandpaper, I have a nice fitting part. I also incorporated a rear bracket to hold the pan, provide a hard mount for my IAT sensor, and a 1/2" tube to connect to the valve cover breather.
