Peek torque comes @ peek VE, the trick is to keep torque or VE as high as possible past 5250 for as long as possible, than you have a engine that will pull hard thru the power band, the longer the torque curve the higher the power band, the more rotational speed in RPM = more HP<disclaimer> this is the personal opinion of a small block engine guy with just a few years of experience, I could be totally wrong
