I'm certain those are the specs cause I remember it was awfully close to one of the motors I built with a hair less cam than I had and I didn't expect anywhere near those numbers.
Damn I wish I could find the one that really stuck out. I believe it was Blue Print that rated a 350 with vortec heads and a 220/224? duration cam at like 405 HP. I kinda just assumed that was not an SAE dyno cause it seemed quiet high.
