im grounding my block to the frame for my chassis to engine ground, i put the strap on the back of the block to the firewall, and a 4 gauge ground from my passenger side motor mount to the sway bar bracket. the battery is grounded to the trunk.

few questions...

do you think a 4 gauge wire be good enough for my chassis ground?

is what i have enough? should i put a ground from the drivers side motor mount to the drivers side frame?

ground strap to block, other side goes to firewall

I would run a 4 ga wire from the engine block to the dash harness ground point near the starter solenoid.

I also ran an 8 ga wire from that ground point direct to neg batt post as well as an 8 ga wire from the neg batt post to the front radiator support.

The 2-8 ga wires might be overkill but I was having some voltage drop problems and the extra grounds seemed to have fixed it.

my battery is in the trunk, and my solenoid is hidden in the drivers fender, sorry for not specifying.

hiding the wires as best as possible is a big concern.

You need a 4awg wire runnig from the battery to the block itself. The stock chassis does not provide the adequate grounding necessary for that type of distance.

I want to measure mine. It doesn't look that tall.
