How did Ford originally ground (body to chassis, chassis to block and block to body) the 1956 Crown Victoria? Is there a better way to do this? Any recommendations?

In the 56 TBirds for instance, a separate ground was installed between the engine and body. The other TBirds (55 and 57) also had separate wires for engine to body grounds. I assume the sedans had something similar.As far as the rest of any of the grounds mentioned, there were no separate wires installed and the grounds were the bolts that held everything together as far as I can determine. Of course, there were grounds for various electrical components that were part of the general wiring.



If you more info on grounds, if its available, get an electrical installation manual.

I dont believe there was a specific earth wire from body to chassis but there was an earth wire from the front engine steady mount to front cross member. It doesnt hurt to add battery cable sized earth wire from block to body to ensure strong ground for all the body orientated functions.

There are actually 2 ground wires originally.One is on the steady rest to crossmember and one is from the left side of engine at rear to the firewall.They are sold as repro parts from most of the regular suppliers we all deal with.There is also a brass grounding "clip" on the top of the cowl on the right side which is supposed to come in contact with the hood when closed.Not real sure of the purpose of that one though.

  

You can never have too many grounding bonds- it all depends on how ambitious you are, I suppose... /Duck

BOO- YA!!!

Yes you can.

Ground loops may get your electronical devises acting funny, althought Y-Block era cars dont usually have many of them.

The brass grounding clip on the cowl was to ensure the hood had a ground to shield ignition interference so the radio wouldn't pick it up.  Remember, this was am radio and solid core ignition wires.
