as doug said, it could be a leak on the air intakes for brake assist, pcv, etc. I think the best thing to do first is to disconnect all those hoses that go to the intake and to the Holleyand put caps in place and do a test.
If you don't already have it, a link in french for the Holley settings:
CARBURATEUR AMERICAIN REGLAGE (free.fr)

Thank you very much for the link, I think it will help me a lot.

I found a first "leak" of depression, the PCV ME Wagner valve which I haven't adjusted yet since it needs a stable idle, I plugged it and it's going a little bit better.
I'm going to check the power valve because in addition to the backfire there are explosions in the exhaust and flames that come out when I keep the engine speed a little high, not when I release the accelerator but while I hold it a little open.

Thank you for all your advice
