Well, so far, I can safely say that my all aluminum battery cable stretching from the rear battery position to the starter junction box at the firewall and then to the starter itself have proven a success on the street. So far starting very well with a well juiced battery.
This saved 3-1/2 lbs over the regular copper wire cable I had for years.

Now if I can only get my hand$ on one of tho$e elu$ive magne$ium K-member$.LOL
