Probably just over 350 HP, that's a way wrong cam for those heads. Those heads have really poor exhaust ports, and thus need extra duration on the exhaust lobes of the cam. You shouldn't be running more than 32 degrees of total timing at WOT. About 8 degrees initial, and another 24 of centrifugal. If you want more, get an XE268 cam.
