350 Chevy squeaks after rebuild

Well, I rebuilt a 350 chevy about 3 weeks ago. I got it broke in and running pretty good. So one day when I was out drving around I thought i would stop and see if the ol' girl would spin the tires. Well, it did, and it did it good. But now after I did that, it has had this terrible squeek coming from the engine. Its not the water pump or any of the pullies because I took the belts off to see if it would still do it. The engine still has good oil pressure, so I dont think its the bearings, but it still might be? I just dont know what else to do. Any ideas?
Thanks in advace,
Logan

Oh, and it doesnt do it all the time, It could be ideling just fine, then all of a sudden it will start. And it doesnt seem to do it after about 1200 RPM.

Just a shot in the dark. Check the flexplate for a crack.

Now that you guys mention it, my old 91 Ford 6-banger squeaked on start-up. Oil pressure was low, so I tore it down for a rebuild. I guess I just never put 2 and 2 together to identify the squeak and passed it off as the belts. Bearings were toast. Just fired it Wednesday night. No squeak.

engine squeek

Stock stamped steel valve covers? There is actually a right and wrong way to install them; incorrecty and the rocker arms will contact/squeek. Look at them from the "front" and you'll see a difference. Just a thought.

That was a good point about the "early" staggered bolt valve covers, you could'nt put them on wrong.

Is it an automatic? My sons 400 started squeeking bad after we got it done. We searched and searced and finally unbolted the converter, no more squeek. Come to find out the torrington bearing in the converter went south cause they set it up too tight.
