Also, just like shown on the 408 motor graph, the torque is very broad and maintains at least 85-90% of peak over a very broad RPM range; Ex: look how long you have at least 420 lb/ft from on a 495-ish peak...over a 3000+ rpm range. IMO that is the sign of a well executed and HP/Tq efficient combo, broad torque that results in a near linear hp curve (which is the rate of HP gain per RPM increase). Broad torque gives you a combo that will work well on the street as well as at the track, don't overcam, keep the Peak torque RPM at a reasonable RPm level for block preservation and let good flowing heads and induction do the HP work above that RPM point to keep as much of the torque for as long as you can.
