Dirtmover, I have a friend who has a 1999 model F-350 Ford truck with a new clip on the front 2005 and his engine, a 7.3 diesel has over 385,000 miles on it and still going strong. He gets 21mpg empty on the highway driving 70mph. Pulling he got 16.5 and that was 12,000-lbs of trailer, horses and tack. He had a 100hp-chip installed at 250,000 and said it worked great!~ He is on his 3rd Ford tranny though, not to bad considering the miles and what he pulls every weekend and hauls trailers for his business.
