Noises from here are really impossible to diagnose. What does it sound like? Any metal in the oil, did you cut open the filter and look for metallic debris? Can you feel anything when touching the pan? Btw, what is a pecking oil pan?

Pull the pan. could be a baffle or windage tray come loose or maybe, just maybe they dented a 350 pan for the 383 crank and the dents are expanding a little and touching?

Your post is a little ambiguous. Did you put on a new chrome oil pan or is this the one it came with? Did it start making the noise after you changed oil? In any case, pull the pan and check out the pan before you do anything else.

obviously you can,t guess you need to deal in facts and you get facts,
by closely examining the problem too diagnose the source.
it sounds like all the valve train and rotating clearances were not verified before the engine was assembled.
if the noise is related to the rpm, it could be the moving parts in the valve train or rotating assembly,
I can tell you that a good many chrome oil pans,
ESPECIALLY THE CAST ALUMINUM ONES,
were built to fit a 350 with its 3.48" stroke not the longer 3.75" stroke of the 383 version of the SBC.
in many cases a couple well directed hammer hits on the oil pan rail will provide the required clearance.
pulling the valve covers and if required, the oil pan would be a reasonable first step,
in locating the source and examining the block and oil pan for indications of the rotating assembly contacting the dip stick,
a loose flex-plate, or flywheel, the rods or crank hitting the windage tray or edge of the oil pan,
is obviously the next step, followed by modifying or clearancing or replacing whatever part is required.
it only takes a minor mechanical contact to make a hell of a racket so look closely
