I'm building a 396" stroker

My 340 blew Sat. nite coming back from a local cruise in while I was racing a buddy of mine in a mustang. I had this crank I had bought years back. I was wondering what a stroker combo like this might be worth powerwise. Heres the details: 340 bored .040 over, 3.79 stroke mopar forged crank, ross pistons 1/16 rings, 0 decked block, balanced, eagle h beams, arp main studs, milodon deep pan, high vol oil pump,lifter valley tray, x-heads done by hughs 2.02-1.60 lots of tricks, 10.75.1 comp, racer brown solid .560" lift- [email protected]" lift, 1.5 roller rockers, edelbrock rpm air gap, hughes HVH spacer, quick fuel 850 carb, electric fan, electric water pump drive, fluidamper bal, underdrive pulleys, arp head bolts, TTI 1 5/8 to 1 3/4 step headers, all MSD(dist,6al,coil) blocks honed with torque plate, block and crank superstock indexed to make sure each throw is 90 deg. I believe thats all I don't know as to the bobweight just yet as I have don't have the pistons yet, just started this little deal but I have everything else. Let me know and thanks.
