I personally didn't like the 460, its great for an RV or a Snow Cat. It never belonged in a half ton truck. It weighs somewhere in the range 650 pounds. Mine repeatedly blew the intake seal in the back, it blew the seal around the oil filter once, actually I think that was caused by the filter, it burned oil like it was free, it constantly stalled but i believe that was just a crappy carb, this motor was no good at revving otherwise it would detonate, I constantly replaced fouled and smashed spark plugs, it did last to 300,000 miles, mostly my dads miles, it got gallons to the mile once while towing a 12,000lb 40' double axle. It refused to run during some of the cold days in our nine month winter. It didn't like to go up hills. The motor never really broke down to the point that it was totally disabled for any long period, and parts are very easy to find. My 400 outpulled the 460, it started every morning, it never burned more than one quart in every 5,000 miles even while towing, the 400 has a longer stroke than the 460, so it developed very decent torque low in the power band and throughout. I think the 460 is overrated. I love Fords, I own nine and my dad owns 17 built anywhere from 1935 to 2003 and encompassing nearly every engine Ford put in a truck. By the way I love our new 6.0L King Ranch F350 4x2 Crew Cab
