I'm using this switch to isolate the battery on an antique car, and it works as I needed it to. It handles the full battery load (starter, ignition, and accessories), and I've had absolutely no problems with it on hundreds of starts.

I'd be surprised if my starter draws more than 250 amps, so I can't confirm that this will work for one of you gearheads trying the same application with a 460ci motor or the likes.
