For God's sake, whatever you do, stay away from the Ford 6.0 diesel engine. I've put over $18,000 in repairs in mine. There is not a diesel mechanic in America that will tell you a positive thing about these dogs. Go on the internet and follow the lawsuits. You'll bleed serious money if you end up with one of these. If you can get a 7.3 you've found gold. I'd even go with a "gasser" before a 6.0. Honestly be very, very careful with this engine.
