early big 3 upgrade

[superhighperf]

i am finaly going through the electrical system in my car and on any other vehicle the first thing i would do is the big 3 upgrade. .you can improve most vehicles electrical system by adding 3 wires. alt + to bat +, alt - to bat -, bat- to chassy . this makes a huge difference on how the alt charges and gets a higher voltage. here is a link to a post with pictures of a honda upgrade.

how would this work on my 69e motor? the alt has a regulator so can i get the power straight from the alt? run a wire from the alt + to the starter. the wire that is on there now is tiny and comes from the harness. boo that wire should be at least 10 guage for 50 amps. i would like to use 8 guage and a 8 guage ground direct from battery terminal to alt.

i would also like to get a higher voltage regulator my guage says 14 volts max and i can get a battery that will handle 15.5.

so, if any bosy has had any luck upgrading those wires, let me know. it makes such a difference on other cars it's got to help my por c e
