Converter Question

I have a 367 with a 904 trans, that has been balanced by the machine shop, with a new balancer and a B&M flexplate. What kind of Torque converter can I use? I know I don't need a balanced converter now, but can I use one designed for a 318? My flex plate has both bolt patterns, and the splines are the same. Trying to get around 2500 stall on the cheep. Was thinking of going with the Mopar one from Mancini, maybe the higher stall stock replacement from my local parts store. the Magnum headed 367 should be around 400 hp.Thanks
