How can anybody make a guess with such little information?

I know 2 things that will cause this. Really bad compression, and gasoline
boiling in the carb when engine is shut off. However, the latter will start
after cranking on it a bit.

Or sometimes just a bad starter (if it doesn't crank when it's hot).
Also, check to make sure the accelerator pump diaphrams aren't cracked
and leaking all over the place.

Yeah. The OP didn't say whether the engine was turning over or not. Like I
said, need more info.

In line with your comment, if he has headers, he may be frying the starter
and it won't turn the motor over hot.

Starter works greate.
After 45 sek with the starter going it starts, and black smoke
from the exathuost.
Engine 289 2v
Year > -67
Engine is 100% original

It sounds like it's just time for a carburetor rebuild.

Have you checked:

cylinder compression
plugs
wires
fuel pressure
fuel filter

Once you get it running, does it run OK?

also check coil for thermal breakdown. condensor should read 5 microfarrats.
and long pink wire in mail harness to the coil maybe frayed or broken
limiting voltages.
low voltage at coil and hence to spark plugs often will keep a acr running
but can't fire in the rich enviroment of a start up condition

It's flooding. Gas in the carb bowl is boiling and spilling down the carb
throat. The cure is a carb spacer, preferably a phenolic one that won't
transfer as much heat. Also, you can get a very thick (about a quarter
inch) carb gasket/spacer. Easy fix.
