With your current setup, a stock converter would be just fine, but 2200-2500 would work also, and be better suited to a 3:23 should you step up to that! The 2500-2700 suggested may be better suited to a 3:55-3:91, or better yet a 3:73 with that combo! JMO of course, but I would just run a stock converter for now until you upgrade the rear end ratio! Stock converters are only $150 or so!
