Odd

White smoke is unburned fuel, water from humidity, or coolant.
As good as it isn’t for your lungs, smelling the smoke tells you what it is.

Smells burt af, I just think its fuel

That seems a quite long run to clear out the smoke in a 75 deg cold startup. my 93 which has profuse blow by and just plain worn out engine will only puff smoke a couple seconds. seems like maybe injectors are leaking down into the cylinders overnight? I'm told that 75 degrees and the engine shouldn't need the GP's but both my rigs absolutely need them to fire up. could one or more of your GP's be not heating up causing one or two cylinders to take more time to start burning the fuel properly? listening to the exhaust in your video is seems one or two are a hit n miss like a couple are mis-fireing. that is a tell-tail sign all of the GP's aren't working or heating evenly.

I would start with pulling and bench testing each GP one by one along with a compression test. I forget which GP you installed, are they the delco 60g's or some other ones?

If You would want to pull those injectors then send them to @Rockabillyrat and have him check and adjust them, I believe a lot of that smoke could be eliminated.

Did that just start happening?

Id say it just started smoking like that, hasn't really done it before, at least in a while

Its only 60°F atm

I have a spare 90 motor in my friends storage unit, could I saw them in or not worth it?

Speaking off, is there anything on that motor i could potentially swap into this one?

 

[dbrannon79]

I would save just about everything. if the motor is good, keep it, you just never know!

Seems to me you're jumping the gun on a different engine. At least do a compression check

100%!!
Keep the other engine, they used to be cheap, now they are getting harder to find at a good price.

Set up your camera to watch the clear line for the next couple of cold starts.

Then if that turns up nothing, I would begin with doing the water down intake trick to clean out all the carbon from the cylinders, it will usually clean off the injector face too.

Then after that, do a DRY compression test.

From there you can choose to spend labor or money on parts (that would get used in next engine anyways). Cracking on injector lime at a time to discover which cylinder(s) are the culprit and combine that info with the compression test. If only one cylinder- swap that injector with a good one and see if it follows the injector or stays with cylinder.

If you are ok spending money- buy a new set of injectors from Leroy but ship them directly to rockabillyrat and have them balanced.
Then watch what that does.

It is possible from the time you got it hot that it smoked a ring or two. But I would diagnose it first. Otherwise if you prefer throwing money at it, buy a new optimizer and have it sent to TSP for him to deflash it, gapless rings, balance lower rotating assy, etc. and still while that is happening, buy injectors from Leroy and send them off to be balanced.
