What did I do to my 1992 Ford 460?
Just installed the Twisted smog box with all the smog elimination hardware on my 1992 F-250 460. I’m very satisfied with the power increase and difference in throttle response, more easily diagnosing the emissions garbage under the hood and allowing the engine to be more open was pretty liberating too.
What causes a Ford truck to lose power?
A weak or failed ignition coil is another potential source of a loss of engine power. Ford Modular engines are well known to have issues with the coil on plug systems. Coils get weak with age and misfire under load. This is often misdiagnosed as torque converter shudder.
What kind of gas mileage does a Ford 460 get?
For comparison my ’86 Supercab lifted on 35″ tires with 3.55:1 gears and ZF5 (~2000 RPM at 70 MPH) gets about 12.5 MPG unloaded highway at 70-75 and 10.8 MPH highway pulling 5500 lbs at 65-70. Truck weighs in around 6000 lbs with two full tanks and myself. Around town and mixed I’ve seen as low as 7 MPG.
What kind of flatbed does a Ford 460 have?
The twisted smog isolator made my 460 run the way it should have from the start! I have a 93 F Super Duty which has a dana 80 rear and a 7′ x 9′ flatbed (in other words it’s a heavy truck) and now she can move out right quick and keep building power until I say when.
What’s the bad side of a Ford 460?
On the bad side, however, the 460 head exhaust ports are extremely narrow and do not let the engine “exhale” to its full potential. The flow on the exhaust ports is so bad that adding a larger cam will completely choke out the engine and provide very poor performance at any RPM range.
How many horsepower does a Ford 460 have?

Why does my Ford truck keep losing power?
However, this is a process built into Ford trucks that runs to rid the extra particles in the exhaust system, and is an emission related recycling process. It can occur almost anytime between 100 and 600 miles of driving the truck. This is not something that requires repair. However, the filter will likely need to be changed around 120k miles.
