Did Ford make any changes to the Horsepower/Torque on the V8 4.6L engines from 1997-2000? I believe the 2000 F-150's are rated at 220 HP.

 

farmerjim97,

The 4.6l has remained the same since 1997 except that all 2000 4.6s are built in the Romeo plant and they now have coil on plug systems. They still produce 220 hp and 290 lbs/ft.

JMC,

I've been scanning through past posts and have seen something about the 1999 and 2000 4.6's upgraded to 235HP. Also, could you explain the coil on plug systems? Thanks.

Certainly not an expert so take my word with some salt. But looking at the manual, the 235 hp 4.6L Tritons are for the F-250LD with automatics. I wonder if the 2K F-150 7.7K rating will get that 235 hp 4.6L as the base engine, or will it be the 220 hp still?

Instead of having ignition coils and wires to each plug, the new Tritons have ignition coils on every plug eliminating the need for ignition wires and if you lose a coil, the engine will still run quite well on 7 cylinders, whereas if you lose a coil on older single coil engines, the whole engine dies. On the older 4.6L Tritons, you would lose 2 plugs for each coil, as I recall.
