Should go without saying if you're doing a cam..
None of that will help motivate two tons of steel to get off from a stop. The power and torque won't be appreciable until 2-2500 rpm, and a stock converter is going to lug that motor down below that for what will feel like an eternity.
If your budget can take it, call and get a decent converter (search around for company recommendations). Be honest about what you do with the vehicle and what you want - something suited to towing would not be out of place, IMO.
