Engine Rattle/Knocking

I have a 95 discovery with 178K miles and recently changed the oil, plugs, wires, and O2 sensors. Was driving today uphill around 60 mph and something on the right side of the engine starts knocking. It would not down shift to a lower gear, even when i had the pedal to the floor. Seems to knock more when under a heavier load. It idles a little rough, but never stalls or comes close to stalling. I usually drive this vehicle around town and never reach speeds of 60+ mph, or put engine under load of a 2 mile uphill drive. I never have any issues when driving around town. I have no idea what to look for. Any ideas?
