Is this at idle or while you driving with the accelerator on?

idle as you stop

Not good, something might be damaged internal to the engine, how is the oil level? I'd have it checked out at your local mechanic before it gets worse.

Is the noise upper or lower

I have the same issue but its only when truck is in drive or reverse but not when its in park and idling. Ive been told its possibly just the exhaust pipe is loose and is rattling. Is this true? Or possible?

low oil pressure is likely the problem, what year is the truck?, late 80's up to mid 90's 302's (5.0 litre.s) were known to have oil pumps that wear out overtime.

It could be many different problems. If its upper noise it could even be injectors. Nothing to do with oil, or it could be lifters or valve noise. If its lower end noise it could be that you have a rod knock or even a spun bearing. Does your truck have an oil pressure guage? Check it to make sure that you have at least 40psi. Beter if between 40 & 60.
