[Sir Swish 10+ year member]

i am doing the big 3 for a friend and i wanted some insight. so i upgraded the alt+ to batt+, and the ground to batt-. now should i do engine block to ground or engine block to batt-? which one would create the least resistance?

I know I've used the alternator mounting bolt as my negative engine ground and run that to the batt-. So I have one coming off the +alt to batt+ and one coming off the alt - going to batt- and then batt- to chassis.
