I used 2 gauge welding cable when I wired my car years ago and didn't know any better. If I were to do it again, I'd probably use 1/0 cable. The 2 gauge has never given me any problems, but I attribute that to it being a small block with strart retard and a PMGR starter.
i had XS Power fine wire 2 gauge in it and over the weekend it started to smoke while trying to start the truck. so i cut the cable and ran it straight to the battery. the truck started 10x better then it ever has. now i dont know if thats from the wire being to small or the master swtch. but it needs to be addressed before the next event.
