Here's engine dyno #s from my 427 S/O

hp 485@ 6,100rpm
torque 490 lbs/ft @ 3,900

FYI the numbers didn't cross at the "magic" 5252.

As to the high rpm Indy type engines, I would suggest that two thing be taken into account. First, they are not "normally aspirated", meaning they are stuffing air in with turbos or superchargers. Second, they have a bore and stroke ratio that would scare you. They often have less than a 1 1/2" stroke. Those engines rely on airflow/manifold pressure and rpm to make hp. 320 lbs of torque doesn't sound like much, but 853hp will break tires loose at 200mph.
