Can someone tell me roughly how much HP this 455 will put out?

Obviously I'm Not a mechanic, lol.. Without putting it on a Dyno can someone take an educated guess as to how much estimated horsepower this 455 engine will put out? It has a TH 400 Tranny with a TCI Torque converted with a Stall 1800-2000. The "G" Heads and "F" short block were both machined, Forged Pistons, Rod's re-sized, Ferrea Stainless Steel Undercut Valves, Proform 66955 HEI Distributor..

Sometimes ignorance is bliss, pull a hole shot and let them wonder.
