FD, of course you can get 50 hp from a cam swap from factory stocker to better cam, but he's already done that. He's running a Comp XE268, which has 224/230 @ 50 with 110LSA. This is a proven street cam which should be good for 1hp/cubic inch with decent heads.
Gaining ANOTHER 50hp from a cam swap will put him out of the streetable range, PP is right. Power band will start at 3500rpm, the car will be an absolute dog around town.
