If I was you I would probably pull the intake and relube the cam and lifters before firing it up. If the cam was previously lubed with something like the Comp Cams lube I doubt there is any left on the lobes at this point.
I put the cam in my 383 a few months ago and had lubed it up with the Comp Cams lube. All of the lube is now pooled up in the bottom of the clear plastic bag that is covering my engine on the stand. The cam lobes are pretty much bone dry now so I will definately be lubing it again prior to startup.
I was pretty surprised that stuff was so runny. I've seen pics of guys using moly lube that looked to have the consistency of bearing grease, but the Comp Cams lube has a consistency more like gear lube so it definately runs off after a relatively short period of time.
