Default 440 Smoke!

First time poster, and new to Dodge big blocks. I’ve got an issue. I purchased a 1974 motorhome on a Dodge chassis a few weeks ago, mainly for the pristine condition of the home itself. Unfortunately the motor part of that deal has a smoking problem.

Upon startup it smokes a bit of white and seems to only run on certain cylinders, and spits out lots of black condensation/fuel (not sure which) once it warms up a bit/throw some rev into it, it seems to idle more evenly.

As it it warms up the black liquid disappears, but it continues to smoke white, perhaps even more than it does when cold. It seems to smokes a bit less when you rev on it a bit.. Black smoke comes out when you hammer it and disappears when the revs catch up, no big deal, surely just excess fuel. Not sure if i’d say it smells sweet like antifreeze, but it could be i suppose (lung issues don’t like smelling exhaust lol). The dipstick sort of smells a bit like gas, i fear the worst.

I should also add that it leaks about everywhere, so the oil consumption issue i’ll greatly attribute to valve cover gaskets. I wonder if i should be pulling this engine to rebuild. I would like to pull it and go over it/reseal on a stand anyways…

Any ideas? Never had a smoke issue on any of my small block chevy’s/big block olds or any of my gas farm engines. It also starts hard when HOT or been sitting, seems to need the starter engaged for extra few seconds to “catch” after it fires. I can post a video of a cold start to warm idle if it helps. Thanks!
