Block Grounds?

Big Bopper · 04-15-2002, 07:16 PM

where do you ground the block at? I know there is one on the rear of the engine on the drivers side that ia attached to the firewall.... is there any others?

The main ground is for the battery at the front left side of the block near the oil press sending unit.I'd ground battery to block,battery to chasis and the one you said at the back right side-one of the trans to engine mount bolts to the fire wall.

You can never have too many grounds. Ford has a bad habit of running a chassis ground to the radiator, which often becomes brittle. I personally recommend a two lead ground cable with a pigtail, and run one lead to the block and one to the frame, and the pigtail to whatever the factory chassis ground is. I also recommend running a separate ground cable from the block to the frame, and one to the firewall. Among other things, this also eliminates any rpm pitch you may hear through your stereo.

Take care,

There are two grounds that attach to the back of the driver's side head. One goes to a wiring harness and the other to the firewall. There is also a ground for the battery that attaches to the timing cover.
