There is just no substitute for cold cranking amps, as batteries are rated. A really big, lorry type battery is the answer, either connect it if you have the room, or use proper jump leads. Those Mickey Mouse Halford type efforst are no good. You need to get a lot of power through those leads and you have to spin that engine over easily and with purpose. A rumbling slow crank wont work.
