Removing emissions clutter for cleaner look?

[David F]

I think the "vacuum block" mounted to the inner fender (below the coil) is part of the fuel vapor recovery system and leads to the fuel vapor tank mounted in the right side quarter panel.  I am relatively new to Z's so mileage may vary....

 

Also, FYI, BSPT plugs can be found at McMaster-Carr in several different metals (i.e. brass, aluminum, steel) and configurations (i.e. hex, hex socket, square).

I'm just getting up so still a little fuzzy but I can only think of the two hoses on my air cleaner box that connect to the over flow bung on the float bowls of the carbs.  I'll look later and let you know for sure.  There is a vacuum block mounted below the coil but I'll be damned if I can remember what it does right now?

The part mounted below the coil and ballast resistor is called a flow guide valve - no vacuum associated with it.  It routes some vapors from the crankcase (the tiny tube on the PCV vent pipe) and vapors from the fuel tank to the back of the air cleaner so they can be pulled into the combustion process.  The only "vacuum" that might be present would be the airflow being pulled into the carbs.

So I finished the emissions delete tonight. I must say, it looks so much better without the chaos of vacuum lines. 

Just force threaded some flywheel bolts from an old ford 302 that I rebuilt awhile back. 

There is an exhaust line behind the breather tube that I decided not to mess with. I removed the anti-backfire valve and it sounded soooo nice but I saw some flames pop out and decided to quickly thread it back on. Going to find a a way to leave it off and use a vacuum hose to direct it away from the carbs to keep that sound.

I can see you have a high performance air cleaner like I had one time.  Bought this motor for the carbs.
