Closing the choke and having the idle rise is a leak somewhere on the carb base or around the intake manifold.
Hook up your choke with the kill cable or wire it open so the choke doesn’t close when it’s running down the road at a higher rpm. At the higher rpm, the choke will close choking the engine out.

Rear of that carb, on the "base plate", there should/could be provisions for a vacuum hose port. Is it capped off? Is it used for your PCV system? OR is it wide open, creating a vacuum leak?
little sprays of starter fluid looking for where the idle picks up to find the location of the vacuum leak. Is this a fresh carb? Did you plug the brake booster hole in the back of the carb with a plug? What is that tapping sound?

Well it’s more than what I expected big leak from the intake adapter plate so I bought a 4 barrel intake put it on. Ended up finding out half the block is running at idle, and half the block is not the side of the block with the steering wheel the muffler on that side only heats up when I give it throttle. Its not just one pipe still cold it’s all four any help?

I don’t think so but I could be wrong

I doubt it was running on 4 cylinders though.

The right side on the dual exhaust is putting out some pressure while the “sleeping side” is barely producing anything feels like a hybrid or something on that side.

weird. Used intake? Did you inspect it for dirt dobbers and Rat nests?

Have you done a spark drop?

First time I did one on a small block, I had a friend ( old Mopar Drag racer) show me, he actually offered to come help. You have to make sure you get the corners good. Big Blocks are easy....

Advance the timing and see what happens. Just pull some in without regard to how much. If it starts to run better, pull in some more.

How do I advance the timing?

First time having my own engine with no help grandfather passed so I’m on my own.
There's a bracket with a bolt at the base of the distributor... Loosen the bolt and turn the base of the distributor in the opposite direction that the rotor spins... Tighten the base bracket bolt when done....

turn the distributor counter clockwise.
when you replaced the intake manifold did you have the distributor out?
also, it's running crazy lean and sounds like it has a massive vacuum leak. plug up the ports and see what you've got going on.

That was a a video I posted prior to installing a new intake it was the only way I could keep it running.
