Question engine knocks ???

I have an 1997f150 with a 4.2l v-6, it hadn't been started in a couple of months(nov-dec,ok..and jan) I started it and a loud knocking sound is coming from the front of the engine....Any ideas on this and how to fix it??? It never made this sound before. A friend said something about a lifter or something stuck????

How many miles on your truck?
How long have you let it run now after having sat for so long?
Does the oil look clean? Is the coolant level down at all?

150k, let it run for 30min, tried an engine flush(5min), changed the spark plugs but no change in the knock. I do remember it tried to miss when I first started it....

You might also try asking in the 4.2 forum which is a ways further down on the main forum page.
Noises can be hard to diagnose in real and almost impossible on here but someone there might have some more ideas for you.
