No oil to top end

According to their "lab": Due to small tiny minute particles small enough to fit through the stock pick-up screen... If their pump can't handle what the pickup screen can't catch, it's a piece of junk to me...

I bought a parts car that had a 360 in it. It had broken the oil pump drive and lost oil pressure. The owner stopped before damage to the rest of the engine. I tore it down and opened up the oil pump. One of the lock wire springs had come out of a lifter and was jammed up in the rotor of the pump. The engine had the stock oil pickup so stuff can get by that is big enough to mess up a pump.
