Total amp draw? Don't know but I'm always thinking "rather too much and not need it than need it and not have it." (paraphrasing Sun Tzu, lol)

Go for eye surgery Monday AM so everything will be on hold for a bit, pull the trigger when I can...or stay with stock alternator with a new belt.....hmmmm....

You didn't say what gauge wire from the alternator to the battery. Where's the battery? The longer the run the bigger wire you need to carry amperage.

I have OO ga wire (I think) to ground on engine block and to the starter solenoid. The factory starter wire going to the starter. Batt in stock location front right of car and alternator wire is factory whatever that is 10-12ga?

Battery is 550CCA and new last year.


Edit: Went and took a look and then took a couple pictures. Forgot that the original wiring also includes a plug and significantly smaller wire from Alt to Batt than I thought.

Yes, it may be ugly, but at least it's slow....no, wait....lol!

I think the Power Master on line catalog has gage wire and maximum length recommendations. Easy to read and follow.

My son has run a CS130 alternator on his 68 Barracuda drag and drive car for many years and it has worked great for him. I think it was from O'Reilly's

With electric fan, water pump, fuel pumps, ECU and Coil Near Plug Ignition it supports a full load.

One of the reasons he chose it was that it came on thousands, if not millions of GM cars and they are easily available at most any auto parts store.
