ok lets see if someone smarter than me can help with this, the engine is a 73 440 cast crank, rebuilt previously 30 over flat tops 0 deck 452 heads roller rockers basically a little better than a stock hp engine...the rest is unknown. I got it from a friend, I regasketted it and a couple caps to theck bearings, hipo pan and windage tray installed:

the isue I have is occasionally if i stop hard the oil light will come on for a few seconds, when hot. I also get a what sounds like a lifter tick occasionally but will go away, like im losing oil pressure. I bust out the snap on mechanical oil pressure gauge and throw it on there.

the cars got 15 40 rotella t in it with a wix filter. cold i have about 70 psi pressure, but the needle on the gauge flutters (this is a new unit, never used so the gauge might flutter) hot ive got 40-50 psi... these are numbers at idle. my question is whats causing the tick and winky light? at 40 psi i would think the light should come on as thats a 3-5 psi switch iirc. today im changing the oil filter and oil, was wondering if a sticky bypass in the pump would cause this or is the engine short for this world? any ideas?
