It seems everyone's dyno is different.......but, If I were dynoing it here.........and assuming it would rev high enough to reach its natural peak before any valvetrain unhappiness sets in.......and has at least 1-3/4" headers........I'd be looking for it to make real close to 500hp with ootb or very mildly reworked(more like "prepped") heads.
