I don't plan on going too crazy with my 05, though I would like to make some decent power with it. . I've been doing some research on torque converters and price, and NADP seems to be the cheapest I've found. . They have a single disc with billet cover going for around 700. . They said it would handle a 500 hp cummins. . I was considering going with that and a Superior shift kit. . Anyone have any experience or heard anything about these converters?? Thanks. .
