Transplanting an S54

Okay, so the first vid is with the belt on and everything spinning, the second vid is just the engine with the serpentine belt off.

Wow, now that's a car I'd love to have. Where in Ontario are you??

As for the noise: to my ear, and comparing to my S54, your video without water pump, alternator, pulleys, that sounds exactly like my engine. The other video (with everything on the engine), it does not.

I'm not smart enough to classifying what sounds are what when it comes to engine, exhaust, etc., but in your first two videos, there are three sounds I hear your car making: 1: is the low pitch grumbling, the dominant RPM dependent engine (and maybe exhaust?) noise?, normal. 2: is a higher pitched noise overtop of that lower noise, my engine has that too. is that the sound the motion of the cams/valvetrain makes? idk what exact part of the engine produces that part of the sounds but I'm pretty sure that's normal S54 noise. 3: I hear a higher pitched, fainter, more "whistley" sounding noise that follows noise 2. That's the sound that stood out to me in video 1 as being your concern, as my engine does not have that.

In the second video (without waterpump/alt/pullies), I could not hear noise 3, which is the noise I thought you were worried about, so that would have lead me to believe that the problem was not the engine itself, but, you conclude at the end of video that it's the engine making the noise, so the noise that you're concerned about is still happening. But I don't hear anything wrong in that one? Just want to be clear on which noise, exactly, you're worried about.

Since there doesn't seem to be a secondary air pump or A/C, the only other two things I can think of is one of the bearings in the transmission area or the VANOS splined gears. Does it still make the noise with the clutch depressed? Did the mechanics stethoscope pinpoint the source of the noise?

Why? Planning a heist? 😉 I live just north of Toronto. I got out the stethoscope today and the upper end is making a lot of that whiniy sound but so is the alternator, brand new from ECS, hoping the alt. will work its self in after a while. I'm starting to think the noise that is so strange to me is the sound of an S54, there is a lot moving in the top end, tested the oil pressure and I think that is where it is suppose to be, the pic is at idle.

Slideways , the sound isn't coming from the trans, it is definitely in the top end and the Alt. I can't get the clutch working at the moment and not sure why, the Clutch MC is a new Tilton 7/8" series 74 unit, all new lines to the slave which is working fine and there is no air in the system, I have bled it in both directions but still my foot takes the clutch pedal to the floor with no more resistance than the return spring. All I can think is that the clutch fork got misaligned on installation. I ordered a new slave just in case.

Just curious, I grew up in Barrie! Would be begging come check this thing out if I was still living around there but I'm down in LA now
