360 build power estimates

Ok i'm recently building a mopar 360 for 67 Dart. For one I just want any advice that could possibly help me out in this build, and 2 i wanna know about how much should this baby fork out power wise. Also what size stall converter would u guys recommend

360 with J heads

bored 40 over
to a 367

Stock cast crank 3.58 stroke

10.2:1 compression
with Keith Black pistons kb107

Decked block for 10 thousands in the hole.

comp extreme cam 274, 230 duration .488 lift on the exhaust side 236 duration .491 lift on the intake side.

mild to a performance port job on the head with valve job 1.88 intake and a 1.625 exhaust

Either a Street avenger 770 or Double pumper 750 undecided still
(would appreciate recommendations on carb)

Headman header 2.5" exhaust pipes

904 tranny

i'm guessin a lil over 400 horses and tq but not much over

I'm also debatin Roller rocker and electric fuel pump, just for a lil more kick.

This will be a street car with some track time but a lot of street strip time.
Also would like to ask you guy what gears would u recommend?
