I am still working on getting my charging system up and working properly. I am in the process of checking all the grounds. Where does the chassis typically ground to the frame? What gauge wire should be used for engine to chassis and chassis to frame grounds.

I ground the firewall to the engine and the engine to the frame. I also put a wire from the bottom of the firewall to the frame.

Ok. Any Input on gauge of wire?

Our ford ground battery negative to some where on the engine just under and behind the Alternator area. Then engine To Firewall.

I guess it don't hurt to ground to the frame from the firewall.

i'm not sure but i think 10 guage wire would be enough.

I have 2' braided strap from motor to frame and 4 other 1/2" straps around the truck, body to battery, cab to frame tail lights to body (flairside) and bed to frame.

Can not ground it too much!

Here's a photo of my braided connection from the engine to the cab and another of the negative battery cable to the engine (as rj said, right under the alternator). I think you can get the braided strap at Autozone or Checkers.

battery cables should be a minimum of AWG 4 but i always use AWG 2 or larger.the neg cable must be at least the same as the pos. but can be larger ,never should be smaller.same goes for the cable going from sol. to starter, can be slightly smaller than the one on the batt. but not larger.
if you have a AWG 2 on your battery you can use a 4 to the starter but not the reverse.

the other wire grounds are typically 10 AWG.

2 ga from the battery to the block. Ground strap...(the 1" wide kind , ) at the rear of the motor, bellhousing bolt to frame. Small ground strap (1/4 style) from the forewall to the engine (valve cover bolts) All connections clean, no rust,junk,funk, paint...etc. Star washers at all points.

just my .02..but it works

The same amount of current (amps) flows thru the ground as thru the positive one. That is why you should have the same size ground cable as the positive one at the battery.

I would not go to the valve cover. I would go to an intake bolt. I plan to put a longer stud on my 460 in the back so I can put another nut on it.
