I agree with Steve. B$M may offer some ok stuff for Chevy's but they sure don't have anything impressive when it comes to Mopars. E-bag the new B&M on the shelf and put in a better converter. Ultimate, Coan, PTC, Turbo Action all come to mind as good converters.

Engine to trans alignment can be an issue but it's really rare and I think if it were an alignment problem it'd take out the front pump and/or input shaft bushings before the converter.
