Yes 625 at the crank is easy with a good tune. I made 640whp with a aps kit on a 02 z06 2 years ago. He does 20-30 min track events and street driving. Its a deal where he has plenty of $$$ but his wife says he cant build a stroker until this one breaks so its obviously its lasting. Now if he was a broke college kid it would have broke a while ago.
