painless sells several different amp ratings, but i think their harnesses come with 70 amp maxi fuse - not 100% on that, though

60-100a depending on your load and charging capacity.
I had a Maxifuse crack across element once, get to 6200 rpm and it stopped charging. I chased my tail on that one for over a year.
Go with a fusible link. I got mine from a junkyard GM wiring loom.

When I put my battery in the trunk I ran my main hot feed from the battery on a 10 gauge wire right from the battery to my starter relay and I used a 60 amp cartridge type fuse for my fusible link. I have just all the stock items on my 63 and I added the Mopar electronic ign , electric fuel pump and the electric fan that I just added a few months ago. Other then that it is just a stock 63 wire harness setup. I use a stock 55 amp alternator and everything has worked fine since 2006 when I go it on the road. I carry an extra 60 amp cartridge type fuse just in case but have never needed it.  Ron

How many amps does the starter, electric fuel, water pump, fan and ignition draw when all of them are on? Find that out and add a safe margin like 25 amps or a little more 
Think you may want to eliminate the starter from that circuit.  Ron

FYI, 10 awg is rated for 35a. You'll never get to 60a, except in SC condition.
The factory used 10 gauge alot on the older cars (60's & 70's) alt wires to the amp meter and battery. Ron
