The original wire gauge on my 67 Camaro is 10. I reused this gauge and connected it to the LS1 alternator. While the alternator is the lower output model, it still produces more amperage than the stock 67.
More recently, I decided to reuse the orig LS1 battery cables and noticed that the LS1 alternator wire looks to be much larger...like about 6GA.
Is the 10GA wire safe/acceptable for the LS1 application?

 

This is a good chart to use

 

Just what I was looking for. It looks like the 10GA isn't gonna cut it.
Thanks very much!

 

I use 4ga for alternator charge cables.

 

I'm wondering what GA I have...6 or 4? Anyone know what size comes with a 98 alternator?
From the looks of it, the LS1 cable will take the short/direct route rather than all the way around the nose, as the 67 did.

 

i think the factory short pigtail is usually 8ga or at least that what it was on the silverado one i got

 

I have taken wires off of a variety of late model GM vehicles with alternators ranging from 102 amps and up... they use 6 gauge wire. The later model vehicles use a smaller "fusible link" wire on one end (about 6 inches long) to protect against shorts, etc.

 

i used 2g but my battery is in the trunk

 

Thanks all!
After cutting the prev mentioned 67 stock 10 ga, I decided to reuse the factory batt/alt wires and chose one of the red 4? GA.
Now I might have another issue which I will pose in another post....
