cam selection

i am building a 360 engine with a target goal of 350-400 hp. currently i have a mopar performance camshaft with 429"/.444" lift 268/276 duration. I found a local ad for two other mopar performance camshafts. one is 284/284 duration with 484/484 lift and the other is 268/272 duration with 450-455 lift. would these be better for what i am looking for or too much? I am trying to make a streetable engine. please give your input on these cams. Thanks.
