You've got to love Hemi builds
My Hemi's very similar to yours 12.0comp, 604cu, Stage 5 millenniums, twin 1250 pro-system carbs on a Hogan manifold.
Was interesting comparing your dyno to mine cos the engines are real close
896torque at 6100 and 1145hp at 7300

Sure will be a hand full on the street AWESOME!!!
