I have a few questions about my smogged out 351m! I know the history and all the parts that are interchangeable from the Windsor to the Cleveland.

I have a 1978 F150 custom 4x4 4spd 4" lift w/ flowmaster 44 series exhaust system. I installed a mild Crane cam, timing chain kit and ceramic headers on a fresh rebuilt engine. Now, I want to add some more HP since its just a stop and go and once in a blue moon trail ride.
I have a Edelbrock dual plain square bore 4v performer intake manifold and a Holley 650cfm Double Pumper w/ Mechanical secondaries all on the way this week. Would anyone know how much horsepower or torque I will be getting out of my 351M after the intitail installation? If anyone else has done the same to there ford what was the out come?
