As a habit, I just ground the heck out of everything. I run extra grounds from the battery to the frame, from the engine to the frame, and the frame to the body. I used to run a samurai with an engine swap and spent some long nights chasing electrical demons that were a result of poor grounds.
For my sub-panel I plan on running dedicated ground buss to the frame and then make sure I have a 1/0 cable from the frame to the battery.
