47-59 Grounding Straps/Wires for motor

[Tempest67]

Hi Guys,

I am just completing the new wire harness install (carbed SBC in a 51 on a S10 frame) and was thinking about grounding straps.

Typically, I see a small ground wire (copper about 1/4 inch wide and 6 inches long) from the back side of a head to the firewall, and then sometimes a larger ground strap (copper about 1/2 inch wide and maybe 9 inches long) from the block to the frame.

Are 2 grounding straps enough?

what do you suggest?

Thanks for your help
