FYI 4 gauge is way to small for 200 amps. Your looking for a 2/0 wire. Go to a welding wire supply place. They sell it, along with the solder on eyelits you will need.

Once you determine the gauge and length of your wire go down to Napa Auto parts. They'll cut the wire to length and crimp on the connectors you select. I just replaced all of my wires during the engine swap and only made one trip to the parts store.
I would not go by that chart personally. Putting possibly 200 amps on a 4 gauge wire is fairly insane. Especially when you consider how hot it is under the hood of a car (yes this affects the resistance of the wire).

I'm definately not one to bash overkill . I actually ran Stinger Expert 1/0 Awg when I did my alternator upgrade. I am also running thousands of watts in stereo and two optima batteries though. Powermasters came up with that chart for output according to their alternators, all of which go under the hood of a car. I'm not sure where else you would put it . I have to imagine they took heat from under the hood into account.
