Top end horsepower and violent acceleration with minimized wheel spin. I bet you with either intake he is well over 400 ft lbs above 3k rpm. More than enough for the street.
If my 414 small block with RPM intake made well over 400ft;lbs. from 3000 up, I know damn well a 512 should be making well over 500ft;lbs from 3000 up.
