Goal: install headers and have a shop fab up a dual exhaust system.

Problem: I am unsure of 2 items that are coming off the air cleaner and believe they will give me a problem when in install headers. So, I am looking for help identifiying them and finding a work around.

Yellow arrow: what is this yellow tube that runs from the air cleaner to the exhaust manifold. How does this come into play when installing aftermarket headers?

Green arrow: looks like a vacuum line that runs from the air cleaner to the side of the carb. If i need a new air cleaner to fix the above green arrow issue how does this vacuum line come into play with the carb?

Any help or suggestions is greatly appreciated.

Looks to be in nice condition. If that was my grandpas truck I would just put the duals on the stock manifolds and drive it the way it is for a while. Don't be in a hurry to make a bunch of changes to it until you make sure it's what you really want to do. How about a few more pictures?

Solid advice I think.

Nothing wild done to it yet. I just gave it a CLR bath to remove a bunch of surface rust, new lower molding as the orginal stuff was really damaged, and a new rear bumper. It is a very unique color combo of green and yellow, but I dig how ugly it is.

Edit: I need better pictures of the paint after it was cleaned with CLR. It really smoothed it out and removed a ton of surface rust. Paint is still in bad shape but it blends much better than the original pictures present with. The last 2 pictures in the album show what the paint looks like now.

here are a few pics.

I agree 100% on putting new exh. system on with old exh manifolds. Being new to classic vehicles, headers can be a headache, even to a veteran car guy.

The quadrajet you have now can be saved. www.cliffshighperformance.com can sell you e kit and all the parts you need to calibrate your carb to today's gas, and the parts are ethanol resistant. His parts are no where near any of the el cheapo prices for kits on ebay, but you get what you pay for...every time!!!
