I feel like there might be something wrong. But I dont know if it's just running rich, wrong timing, bad intake gasket, bad head gasket, or all of the above.

Looks white, condensation, water. When its cold remove the rad cap and start it up let it run and see if you have any bubbles in the rad, might have to rev it up to get a head gasket to leak when it's up to temp. Pull the spark plugs and see if you have a clean one.
 
Before you get too crazy....what's the temperature swing right now where you're at, and is this happening after the car's been driven and is good and warm? Is it garaged, or parked outside?
 
Wow...THis must be what a Veterinarian has to deal with!
The patient gives you only a tiny sliver of information and the Doctor has to do all of the guessing?

I just looked it up on the weather channel, 54*, 82% humidity, 49* dew point.

So it could just be condensation in the air.

Yes I thought he should start there, and consider the nighttime temps vs. daytime...heck even my wife's new car blows some steam for a few minutes on the first startup, since our weather's been getting colder at night.
 
Check out the license plate number....LOL

OP, I see a line of black soot on the floor... is that on one side only? Has this car not been started or run for some weeks or, months?

Dont really know what info you would need since I dont really know what I'm asking :)
 
You didn't describe the engine, the equipment, the gasoline you use, the current timing setting, the static compression ratio, the condition of the spark plugs, the change in fuel economy, the cranking compression numbers, the loss of coolant, the leaks or noises...
See where I am going?
To get help, you need to provide information. Why should anyone have to ask you all these questions to give you help? Why would you make it hard for people to help you? These forums are full of nice and helpful people but you gave almost nothing for people to help you. You made it harder than it has to be. It is also like trying to get directions from a guy that cannot speak.

The black line is more on the left side of the car but still on both. Looks like its sut and water mixed. It also smokes more on the left.
The car was started yesterday also but before that not for 2 weeks. And kept smoking like that after it got hot but not driven (hence the reason I think it might be getting water into a cylinder)
Oh and it also started running pretty bad and both backfires out of the carb and exhaust (timing issue and running rich I'm assuming)
The car has been smoking like that every time i start it for the whole summer. Ofc could just be water concentration in the exhaust.
I mainly posted this for fun and I don't have any specific questions. I suspect some fault in the ignition system but hey I'm pretty new to this. I'm going to be replacing the entire ignition system for msd anyway.
 
Yes, it is sut (soot) and water mixed. OK for being out of both sides; that would be normal if it is rich.

If the water vapor never goes away, then it is likely to be water into a cylinder; the water vapor ought to go away after about 5 minutes of running, even if there is water setting in the exhaust.

Please pull all of the spark plugs, and take pix, and show them here. Then replace the ignition system and see how it runs.

Does your carburetor have an electric choke?

Is there any abnormal stuff in the valve covers that looks like brown milk? Probably not, but something to examine.

Allright I'm sorry I didn't provide any info at all just sort of sharing it :p But here we go :D
Engine is a 78 block 360 with stock internals (I think) with the original for this car 73 340 heads (same as 360) surface planed to oblivion. Engine has new edelbrock performer rpm intake and a 600 cfm volley street warrior. Stock compression I'm guessing. New spark plugs, old once were coal black. I'm running the engine on European 95 octane which is 91/92 in the US I think? The car has some shitty headers that are mangled bad to make them fit and hits the idler arm. They leak in a few places including the gasket on the left side. Stock electronic ignition. Msd wires. Engine does loose coolant but there is a small leak at the radiator so cant know if its leaking anywhere else. When the engine is initially started and is on the choke witch is electric it smokes black. If there is anything I missed I'm sorry and would be happy to provide it.
Thank you :)

Have not noticed anything in the valve covers but now that you mention it i have seen a slight creamy something on the dip stick.
It does have an electric choke.

It's not very hot here about 10°c which is about 50° Fahrenheit. The car Is in a non insulated repurposed sheet steel barn. So basically protected from rain, wind and snow. Car had been running for over 5 min when the picture was taken
 
Hot or cold. Pull the dipstick. If the oil looks like milk or there are bubbles you may have to pull the intake manifold and replace the gaskets. It could be anti freeze getting into the oil.
 
Even after 5 min you probably still have water in the exhaust system (condensation at your temperatures)...
It takes a while idling to really warm everything up. Drive it around the block (when there are any :)) and see
if it still smokes.
...and it is probably running dead rich when you say your old plugs were black.
 
I would think about some diagnosis.
 
Holley.
Needs proper tuning.
 
Well if everyone else gets a shot...lol
End studs on headers leaking, steam.
But 1st it looks like regular old condensation.
 
Elis, I have similar weather conditions in the spring and fall. Had a 318 with dual exhausts and it acted the same as yours does. It took a long time to get the exhaust system to dry up. The colder the air temp the longer it took. Some times I had to drive it for 15 minutes using lots of throttle to get the water out of the exhaust system. I did this to get the water out before I parked it. [for a week or more]. The black soot was common in my engine, too. When the water builds up on the next restart, it turns the soot into a liquid, and spits it out when you jab the throttle. All normal.

'Smokes black when cold' is likely a choke that is out of adjustment. Pull the air cleaner and plug the little vacuum hose to the air cleaner. With a cold engine, start it. It should rev kind of high. Kick the throttle down to lower the engine speed. It should idle smooth. If any black smoke is seen out back, open the choke plate a little and the smoke should stop. There is an adjustable rod system there. Either a screw or bendable rod could be used. Make a small adjustment and test it after the engine cools down. Repeat.
 
Water laying in mufflers,a 1/8” hole drilled in lowest point will solve some of the issue. For every gallon of gas burned ,a gallon of water is produced.
Short trips, or starting and running for a few minutes without getting exhaust hot will do this too.
