So I had to rebuild my 400. in doing so I put in a new cam with a duration of 298/303 and a lift of .466/.488 and an edelbrock carburetor with 850cfm. How much hp/tq do you think this will add?

Just getting my 400 running again. Any idea how much hp/tq it will pick up with a little bigger cam and 850cfm carb?

Besides the cam, have you done anything else to the bottom end? Are you adding a power adder or bigger carb? They all have an effect on end HP.
