Grounding the engine

This is how I grounded every vehicle I owned. I buy a bunch of what ever gauge cable, for normal use 4 Gauge is fine. I use one of these crimping tools in addition to a small torch and solder. Cover everything with shrink tube. I used what ever lugs are needed, chose from these . I use these for connection to the battery. I go from the battery to the frame, from the frame to block. I also go from the battery to the radiator support with a piece of 10 gauge or so. And from BOTH cylinder heads, assuming it is a "v" engine, 10 gauge here as well. And if it is a vehicle with body bushings I will run a piece of 10 gauge in at least one sot from the frame to the body tub. Overkill? Some will say it is. I have done more than one EFI swap where stuff runs on 5 volts or less. Often stuff is in milliamps. So if your grounds are not up to snuff YOU WILL have troubles. Any and all connections get wire wheeled/dielectric greased as well. I try to use external tooth star washers every where as well.
