I have used a buss bar with numerous #8 screws as my firewall earth. I have run a #12 wire from each end (for redundancy) to bolts very close together on the firewall.
I cannot remember taking off the powder coat at the back of the engine mount and am concerned that I may not have a solid ground between the engine and the airframe. I am therefore considering running a #2 cable between the engine strap and one of the firewall bolts mentioned above.
Would that be OK or is the current from the starter going to be too much for the thin firewall and fry it?
