my Dads 85 has a 454 running 8.5:1 compression (runs on 87 Octane) and it's putting out 450 horse 500 ft-lbs roughly, the only real difference is that it has a set of World heads and the biggest long tube headers he could find/modify.
The Torque curve is all bottom and mid range and it's rev limited to 5000 rpm via MSD ignition, if your interested ill have to get the technical info as this was a custom ground cam designed for off road drag racing and mudding.
