145amp alternator to starter wire gauge?

[beaterku]

Quick question. I was laying out the routing of my truck and engine harness last night and a question popped in to my head. Currently, I have an AAW harness on my truck. With the 350, it had a 10ga wire that ran from the alternator lug to the starter. I was going to use this same setup and then I started questioning the gauge of this wire. I think 10 ga is too small for the 145 amp alternator. What is everyone running? I'd like to keep this wire on the starter lug to keep wires off of the batter. It could be done in a relatively short run under the throttle body and down to the frame rail and over to the starter. Maybe 5' total. I was thinking 8 ga. Thoughts?

EDIT: I did some more digging and Painless offers this kit rated for 190amp: https://www.summitracing.com/parts/prf-30700

Maybe something like that is the ticket.

I'm also going to contact AAW and get their input. Edit again, AAW recommends 6ga for the 145. Sounds like I’ve answered my own question haha
