70 Dart. Swinger

The dyno sheet shown is labeled for a 331 cu in engine. Is it a true sheet from your 444 cu in engine just mislabeled? How much boost did it take to make 1043hp?
I thought he told me it was 444ci, no way it is 331ci, i will ask again. It made 10 lbs boost and is tuned with that pully.
