Yeah, Don, the 347 pulls like crazy - torque curve is nearly flat from 2100 to 4500, then falls off slightly to cross the HP line at 5500. With a light car (have not weighed it yet) it is a blast to drive - more power than I have ever owned before, bar none. My 5th gear OD (0.64) lugs down quite a bit below 60mph, but then in 5th it really wants to cruise at about 80mph or so
