Carb Airbox, Input appreciated... Options

[stepuptotheMike]

So I have Weber 44s on my car. When the installation was done by a previous, previous owner, there were some aspects that were less than detail oriented. Items such as the following:

-Fuel Vapor lines from the front (car is a 73) just dump into the engine compartment. Assuming this contributes to fuel smell in car.
-Crank vent is basically a hose with a tiny air filter on it, suspended over the engine case... this leads to oil film all over.
- No head breather ports. Heads were never drilled/tapped for them, but I don't think my venting is adequate and it's causing oil leaks.
- Carbs in general are just loud. I want to hear some throat when I get on it, but don't need it all the time.

So in reading through various threads (especially the ones on the breather setups folks have posted recently) I started thinking about how I could solve all of these problems in 1. Creating a legal setup that would pull the fuel vapors and case/vents into the carb intakes..... and quieting things down a little bit.

So I thought about creating a single airbox that would install over the combined carb setup. Ideally, I would think plastic would be the medium of choice, but I have no clue where I would start.... so then I started thinking about fiberglass. Granted, I've never really built anything with glass, but it's fairly cheap and if it doesn't work I figure I'm only out my time and a few bucks. Plus I learn something in the process. I figure I could use techniques similar to those that the custom speaker box guys use to form shapes and build the box. This would just be thinner.

So I came up with the following crude drawing to illustrate kind of what I'm talking about. I would appreciate thoughts on this concept. Shoot holes in it as you see fit. Been down this road before? Know somebody that tried something similar?

Thanks in advance.... Mike
