I use that one on my setup as the 65 amp I was using couldn’t keep up when the whole system was in use with the electric fan setup. Switched over and haven’t looked back . @ idle with fan running 13.4 volts. I have the shiny one . Make sure you run a earth wire from Alternator to chassis if your using Alloy heads. Just to add I used crackedbacks alternator cable that he makes which takes the higher amp load off the older wiring system .
