Frustrated engine wants to die at idle

Just venting here cause I am not sure what to do. I have a 68 valiant. I rebuilt the motor with 500ci stroker kit from 440 source. Stock edelbrock closed heads with Harland sharp adj. rockers. 292 509 114 mopar cam. I think 9.5 pistons. M1 manifold 750 street dominator carb 72 jets front and rear 4500 elevation. Msd digital 6 box. Full aero motive fuel system with solid 6.5psi 3400 stall converter 323 rear.
So I start it up and seems to run rough. After a minute or so it seems to clear up after revving it up a bit. Get it warmed up then while idleling it seems to want to die if the idle is not up. If I give it gas it just kinda does nothing or feels like its barely running then will die.
If any of that makes sense and you have any ideas or suggestions please let me know.
Thanks, Rich.
