Building a 390 when i get home.... Looking to get lots of high end torque and power all over the place, want to know what others have done to achieve numbers in the 5-600's on natural aspiration.

I've got the edelbrock alluminum heads, scj size valve.
2x4 setup off of a 63 1/2 galaxie
Hooker Supercomps
Bought a cam:
Intake Duration at 050 inch Lift: 211
Exhaust Duration at 050 inch Lift: 223
Duration at 050 inch Lift: 211 int./223 exh.
Advertised Intake Duration: 265
Advertised Exhaust Duration: 275
Advertised Duration: 265 int./275 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.484 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.510 in.
Valve Lift with Factory Rocker Arm Ratio: 0.484 int./0.510 exh. lift
Lobe Separation (degrees): 110
Intake Valve Lash: 0.000 in.
Exhaust Valve Lash: 0.000 in.

Got the MSD 6al setup, coil, dizzy, box
Got an electrical fuel pump
Got a true roller timing chain
The 390 im working on has 10.5:1 factory compression.

Anyone else have something like this or somewhat similar? What can I expect when I put it all together? What can I do to improve it?
