Default LS1 starter + stud size

Anyone know the size of the + stud/lug/bolt on the stock LS1 starter? I am replacing the battery to starter cable, and need to know what crimp connector to get.

It's quite small... the nut on the stud is listed as M8 x 1.25.

So, the 1/0 cable that I bought for that connection is a waste.

Factory cable is 4 AWG. 1/0 might be a bit of overkill lol

Is there any benefit to replacing the factory cable with anything larger than 4AWG OFC cable? I could save the 1/0 for distribution block wiring later.

Did some more searching, and it looks like the LS1 starter pulls about 270amps, so 4AWG is plenty.
