It sounds like you have a flooded engine and the cranking speed is too low. I would put a set of dry plugs or burn the tips of the existing set and put them back in. make sure that the cranking speed is OK, if the starter is not spinning the engine fast enough, it will flood again, I have always used a minmum of 800 CCA battery with this V8 and made sure my starter is in a good shape in addition to its associated cables. The ground cable suggestion in the other reply is correct.
