Hey everyone, first post here, thanks for looking.

I swapped a 1970 Olds 350 into my Monte, built the engine myself, my first time ever doing so. Got it up and running but it's making a horrific squeaking sound, which you can hear in this video:


There was no change to the sound when I ran it for a moment with the belts removed so I know it's not a belt or a pulley. And I do have adequate oil pressure.

I need to do some more poking around, maybe with a stethoscope, but I'm on the road driving a truck right now so I was hoping you guys could weigh in and let me know if it sounds familiar or if there's anything in particular that you think I should check. Thanks

It's just your Monte screaming because there is an Olds in it's engine bay and somewhere there is a Cutlass screaming because someone put a SBC in it.

Ok. Out of curiosity, do you happen to have a metal flexplate cover on the trans?

Did you pull the valve covers while it was running and making the noise?

No, it's uncovered right now. And no, not yet. Are you thinking bent pushrod? Broken valve?

I keep looking stuff up on YouTube and I find a lot of knocking videos and not much squeaking. Very frustrating

I personally don't hear anything that would suggest valvetrain noise.
I would like a new video with no belts and enough light to see the engine.
