John. I hope this didn't happen to you. It happened to me. I wouldn't had beleived this if I didn't see it for myself. My 428, not a Cobra Jet Block, had cracked in the # 2 and 4 main bearing journals from crank to camshaft on both sides of the drilled oil galley holes. I had opened up the oil holes in the mains as you probably know they do not line up with the bearings. The same thing happened to me with the oil pressure. One day I had 80 psi hot at 3000 RPM hot. After a race it dropped to 55 psi at 3000 RPM hot. I didn't find the problem until I removed the crank a year later. So, look for this. And I hope I'm wrong.
