Re: 440 pushrod problem
You need more oil to the top of the engine. Start by replacing the 3/8 oil pick up with 1/2 inch, and high volume pump. Do you use lifter bore bushings? Also, run additional oil lines to each oil galley by tapping into them and oil supply line tapped into the block near the oil pressure sender. Problem solved.
