Squealing Noise and Oil to the Rockers

I suggest you coat the threads of the crank bolt with Anti-seize compound.

This was my squeal problem!
Enough to just barely hit my cover and only could tell when i cleaned my cover real good!

What am I looking at?

That's what I was wondering... but it looks like a couple of oil slingers laying across a level that's mounted in a vise... what threw me off was the top one, looking through the timing cover at the dirt and weeds underneath lol

I see it now. It's hell having 1 eye, lol!!

What, a bent slinger?

Not bent one looks deeper.

Correct, deeper slinger at the left, ever so slightly. Looks like the one on my LA block at first glance.

Not going to say this is your issue, but the Federal Mogul 1094M set has one bearing pair that has a different number. It goes on the number one main journal, and has a chamfer that is on the front for an oil relief. In Clevite sets, all bearings are the same except for the thrust main of course, but the Federal Mogul set has three of the same for mains 2-4-5, one thrust 3, and one for the front main. I ran into this issue when I built a an early (small dia thrust main) for a 440.

The timing cover as i was trying to show was a slight glaze to it and the slingers was different in size.
The one on the left was a little taller and on the right i had an original from a 440 i had laying around!
It squealed like a belt but this was all my noise problems as i put the original in and the squeal went away.

Sorry for the delayed response. Mystery noise is gone - problem solved. After removing the timing cover and found nothing - reassembled and ended up stripping the crank bolt. Thought I needed helicoil - watched a video on how to helicoil a crank. Did not look like fun. Since the bolt was stripped, I figured the crank was ok, so decided to re-tap the crank. Ordered a 3/4 16 tap and had at it. Re-tapped the crank as much as I could - new crank bolt and an extra washer - put it back together, started engine - noise was still there.

Did I spin another bearing? Newly rebuilt motor? Quite possible. Somewhere in this thread somebody mentioned a vacuum leak. In fact my neighbor came over and said the same. Then it dawned on me - before the noise started (there was a time after the rebuild that it did not make the noise), I was fighting what I thought was a vapor lock issue because of stalling periodically. I had read somewhere that installing a one inch gasket for the carb could help. So I thought that the noise may have started when I installed the gasket. Rushed to the car - removed the one inch gasket - had another flat gasket (to hell with the vapor lock issue at this point). Started the car, warmed it up - noise gone. Drove around a few days - no more noise. Ultimate test - reinstall the gasket - noise was is still gone.
So - I leave it at that. Problem solved - possible vacuum leak. Ended up replacing the old Edelbrock 750 cfm with a Holley 670 street carb. Car runs great except for a little hesitation and that darn kick down that doesn't work.
So there you have it - car runs great - no noise. Now I can start addressing the cosmetics.
Thanks for help and advice. since I am fairly new, i am not sure I can help anyone else in this forum - as an old guy, you never stop learning so maybe I can - one day.

Any chance that gasket may have shifted just enough to cause a vacuum leak that would shriek air out a crack against the intake, or perhaps turbulence between the gasket and the venturi bores?

Well, at least you found it. These cars can drive you nuts!

On another note - don't drive that car another mile until the kickdown is adjusted - you'll cook that tranny in a heartbeat.
