This is a very good work or farm truck.
The gas mileage is 9 to 10.5 at best.
For a 460 engine, this truck is very slow.
The replacment cost of the catalytic converter is over $400.00.
On the F250 and 350, especially with the 460, Ford put really small exhaust on them. I don't know why. But I've talked to several people who say a nice big aftermarket exhaust, "Flowmaster", really makes a huge difference in mileage and power. Try headers, new cats and the rest and you'll be happy.
The 460 has a lot of hidden potential. You should start out with a good intake, header and exhaust upgrade. Get a good 600-700+cfm carb, get an RV grind on the cam, 3 angle valve job, a set of headers and some nice 3 inch pipes straight back, that'll wake that big powerplant right up. If you want to go wild, you can plane the heads, thinner head gasket, bigger valves, port and polish the heads and intake, MSD or equivalent ignition system, higher compression pistons and so on. With all those mods, you would probably be pushing 300 horsepower or more.
All around I think the truck is a hard worker and trust worthy. the power locks on the driver side become weak after a while and sometimes fail. I agree that the truck is slow even though I have the 5.8 351 engine. the one true fact is it has a lot of low end torque and will pull everything I have thrown at it.
I think this is a great truck. I have the 5.0 and it's a smooth running engine. Its not the XLT, but its just as nice.
You can get a great performance Catalytic converter for $138 and free shipping. I found it at Auto Parts warehouse online. $400? No way.
