Do these 440 dyno numbers look right?

That seems soft to me. Around 410hp with heads that should go 250 out of the box and a cam past .500 lift? No way. Something's amiss. Sounds like some of the details are sketchy. Were the heads corrected? Were the springs and retainers replaced? How many miles on it? It seems to me to break up early - does the Atominc system learn or do you tune it?
