Truck runs weak
95 f350 460. It seems to have low power since i bought it 8 months ago. It had all kinds of power now it bogs down after 4th gear. Its a 5spd. And sometimes after its been run a few min it will keep cranking before it starts. It doesnt always do this tho. New plugs wires cap rotor fuel filter and fuel pump. Not sure what else to check. Its a problem that comes and goes.

have you checked and confirmed it is getting fuel all the time. Use a fuel pressure gauge to check.

Run the KOEO tests and CM (stored code) display. I agree with also checking the fuel pressure.
Be aware: new parts does not always mean good parts.

Mine ran like a dog till I advanced the timing to about 15 deg. Big blocks like timing. Just watch for pre-ignition.
