Default Dyno numbers for forged 355

Hey guys, my car recently blew up thanks to a very cold night, and a 150 shot. Right now a forged 355 with ported heads and intake but with stock valves, custom comp cam, little bigger than cc 306, beehives, hardened pushrods, 58 tb, pacesetter lts, offroad y and cutout before the flowmaster is being put into it. Also, a 150 wet shot will be used. My question is, what numbers can a hope to achieve on the motor and the nitrous?

my 355 made 525RWHP on a 150 shot thru a TH400 and a 4000 stall...... was about 675hp at the flywheel....

6" rod 355, stock crank, SRP pistons, 11.75:1 CR, stage ii LT1 heads, ported manifold, long tubes, 58mm throttle body..... standard stuff.... TNT 150 shot...
