I'm with you Tim, about peak torque being the optimum, but on the 427 for instance, that's 2900 RPM, and there's plenty of torque available to throttle down to 2600 or 2700 and still be on a plane in my 38 Express. 2900 probably would yeild good fuel efficiency.
Hey, as long as we're talking torque, how about this one! This baby obviously had enough power out of the hole to get all those skiiers out of the water. Pretty cool photo, eh?
