460 D9 Series Cold Start / Engine Trouble

Is this noise something significant I need to worry about? or should I let the engine run and warm up to get a proper air fuel mix and burn off any sitting oil before jumping to any conclusions?
Even though this thing is a nearly indestructible beast I don't want to cause any further damage to the engine. I just don't know if I'm being paranoid and should let the thing run and warm up or go ahead and replace oil, gas, check filters, pull and check the plugs, etc. or start thinking there is something else significantly wrong.

This is a "franken engine" I can't confirm if the carb exhaust manifold, or other parts are original with the block.
There is no significant smoke coming out the exhaust.
Gas is 3 months old with some stabilizer in it.
Truck ran perfect when it ran last.
Have never heard this before after a cold start

That's something to worry about for sure. from the video it; is hard to tell what it is but unless it's something rattling on the fender it's a sound that requires locating.

Sounds like the timing may be advanced too far. but that's not causing the noise. sounds like something ratcheting, maybe the oil pump drive ? lots of things it could be , fan hitting the shroud ? maybe pull the belts off and start it to see if it's an internal or external problem. it's not impossible you have a water pump or something failing.

It made some new noises and some white smoke started to flow from the driver side of the engine compartment.

Here's a video I took of the engine on start up.

First, the engine is not spinning enough when the starter is turning it. As mentioned, it could be the timing is advanced too much. It could also be a host of other things: weak battery, weak starter, sad wire connections, an incompressible substance in the cylinder(s) (water, fuel, etc.), etc. I couldn't see the white smoke on the video under the hood. You should try to identify & repair whatever is making the clattering noise. It might be minor & it might be significant. As suggested, you could remove the drive belts and run the engine BRIEFLY to see if the noise is external or internal. Be sure all your fluid levels are correct. If the noise is internal you could try to locate it by using a mechanic's stethoscope.

That ignition coil is bouncing a lot above the valve cover. Might secure it better and give her another go.

Yea ha I noticed that too, it doesn't budge when I try to bounce it with just my hands but good point and obviously good to check.

I think I'll check fluids, replace gas, and see how it goes with the belt off for a brief run.

It is but it isn't the source of the sound, it was matching the sound briefly until that sound made a ratatattat and the coil didn't connect/bounce with the noise.
Technically those MSD coils need to be vertical as well. But mine is installed in the same orientation..

sounds bad. maybe major, maybe minor, the hammering/ratcheting is bad. could be a head gasket, intake gasket, carb gasket, fuel line, float, what ever. Timing. bad distributor, maybe all of the above that nice lady speaking about the sounding bad was right.
