Power ratings on a 72 olds 455 rocket?

Guys all around the web I find conflicting power ratings can you pro's help me out, I found a totally intact stock 1972 olds delta 88 with 455 Rocket 4 barrel engine and seriously am considering this as an upgrade to put into my 1979 TA.
My car came stock with a paltry 185 horse 300 ft pounds of torque, so picking up 100 horses and 100 lbs of torque or so would be a hell of a deal for the 600 bucks this cream puff car would cost me

Can you guys give me the REAL numbers or steer me in the right direction?

It doesn't matter too much.That engine is 39yrs old,so it won't be making that exact amount anyway,but you will still notice the difference from your original TA engine.If it runs good,then maybe you can run it awhile before rebuilding it.
