I really appreciate all of your responses. some of you are asking me questions about engine specs so I'll try to answer . 428CJ iron heads( rebuilt). .002 clearance (rod & main). comp cam ,M57HV
oil pump. My engine builder started and ran in the engine, I feel this was done properly.
Oil pressure (cold 45 idle 65 @3500-4000rpm).
Oil pressure (warm 10-15 idle 40-45 @3000 & 50 @ 5000) I currently put in mobil-1 10w30. I dont feel satisfied with these pressures and think my problem is the un-plugged lifter galleys.The engine builder dose'nt think this is a problem .However he is willing to help me try to improve the pressure. By the way this builder is not a ford man,(my tuff lesson). This is a great web site. Thanks again. LT.
