If you still want a useful truck after the cam install, I wouldn't run anything larger than a 3200 stall converter. Gas mileage will suffer and towing capacities will be depleted.
I'd recommend a Precision Industries 2800 10.5" multi disc lock up converter. You should still be able to stall flash up to around 3200 rpms with that stall. Select a cam around your components and the use of the truck. If it will be your DD truck, I would keep the stall at 2800. If willing to sacrifice a few things, 3200. After that, track truck.... good luck.
