Wandering around the engine on my '80 i saw that a braided copper ground strap (see photo) connected to the engine by one of the intake manifold bolts is just dangling loose on the other end. Does any know what it is supposed to be tied to? It can go too far so I suspect it might be intended to ensure the potential of the aluminum manifold and the iron block are kept equal to prevent electrolytic corrosion. 

ground strap one end looseAnd as long as I'm here, does the white wire running through the cap go to the tach.

I believe the ground strap is supposed to go to the ignition shielding. It appears your car no longer has the complete shielding/cover set-up.

The wire in question is the tach filter, and yes, it does go to the tach.

Right you are - all that shielding just got in the way. I took it off so long ago I forgot all about it. I never seemed to miss it. But it's in a box in the basement if my descendants or, more likely, the guy who buys it from my wife the day after my funeral, wants it. The back story - She has hated the car since our first date (1985).  I let her drive it and the first time she hit the gas the car lurched off the line more than she expected and the seat slid all the way back as it wasn't locked in. Being 5' 3", she couldn't reach the pedals and was in panic mode. Since then it's been a love-hate relation - hates the car but loves me (must since i have steadfastly refused to part with it, the car, that is, well her too).

Good Morning. I have an '80 Vette and you should have a wing nut( or a stud looking for a wing nut)on the firewall where the plastic Distributor cover was tied to the firewall.It also served as the body ground strap that was connected to the lower valve cover bolt,below the valve cover. I hope this will help..The tubular piece is exactly what Noel states filter for TACH..

Have a great day and good luck.
