I love my 71 350/350 combo. That being said though, I drive a 2007 3500 6.0 with a fully loaded utility bed on a daily basis. I weigh in just shy of 10K without pulling anything and I still average about 11 MPG. When I drop the hammer on it on the highway I am not at all disappointed. Yes, it does run in the higher RPM range, but that does not bother me. I would put one of these in my truck in a heart beat if I could afford it. I love the dependability and overall performance. Just my opinion.
