Do you think this 302 is 400hp

[snowgoer]

I am looking at buying a Backdraft with a 302 in it that supposely has 400hp. The motor was built by Rolling Thunder Race and Engineering from Boca Raton, Florida in 2004. The owner faxed me a spec sheet from them and below is what it has listed on it. I was wondering if 400 hp is close based on these specs. Any other thoughts on this set up???
