How much power will I make

Howdy gang, I'm new here and building my first blower motor. I'm looking for input as to how much power I can expect to see with this combo. Here is what I have:

540 BBC, AFR CNC 357 heads, solid roller dur. @ .050 255/262, lift .647/.650, Accel DFI, #160 injectors, 2 3/8 tube headers, 4 1/2 collector, Non intercooled, F-2 blower with pullies for 20 psi (race) and 10 psi (street).

I have a 79 camaro set up for L/S that I'm putting back on the street. The car has been 5.0's at 140 plus with a NOS 540. The motor was making around 1400 HP with 2 kits. I'm hoping to duplicate those numbers in race trim. Am I dreaming with this combo? Any advice is appreciated.
