Default ENGINE OIL PRESSURE

ANYBODY GIVE ME ANY HINTS ON WHY I'M DROPPING ABOUT 30 LBS OF OIL PRESSURE AT 5200 RPMS IN A DRAG BOAT WITH BRAND NEW 454. COULD IT BE RUNNING OUT OF OIL AT THE PUMP OR IS IT SOMETHING MAJOR ANYBODY?

I hope you're not using a Fram oil filter.

Just a thought...Does this engine have a "stock" oil pan & a high volume pump? I've seen this happen before. A high volume pump can suck a 4 qt pan dry. Just something to look in to. JMO

Have you plugged the bypass above the oil filter. I've seen them open to bypass and pressure drop. The first thing I would do would be to cut open your oil filter and look for any metal. Nip that in the but first.
