Im swapping a 93 350 into my 1987 Jimmy and I have to pick up new wires for the starter to battery and for the ground but I'm not sure of what cranking amps or anything really I should get and the guy at autozone told me just get whatever it had before but I received the truck w/o a battery. Can anyone help me out on what battery would be good? I know it came with a side post because the negative wire is still in but I want to get a top post to make it a bit farther away from the mud and dirt.
