After curing the bog issue she ran out of gas, I fueled up her up with 93 and she'd start, but not idle where I had her previously set (750-8) if I didnt keep the rpms up it would die. When I set the idle to around 1000-1100 it would run on its own, but do this annoying wandering idle... it would go from 1100 down to 600ish and bounce around then eventually die.

When it was running I was getting about 6-7psi for fuel, I charged the battery with my truck just in case and changed the fuel filter (smaller inlet so fuel dropped to about 5psi with new filter) and it didn't change anything.

here are the specs and some vid's I dont know where else to turn (everything is new or rebuilt)

350 4 bolt main
4 relief flat tops
eddy air gap
holley 750 vac sec
lunati 60103 (Advertised Duration (Int/Exh): 268/276
Duration @ .050 (Int/Exh): 227/233
Gross Valve Lift (Int/Exh): .489/.504
LSA/ICL: 110/106)
eddy performer rpm heads 64cc 180 runners
new 1 wire alt wired to + on starter
AC delco HEI
20* initial timing

any advice would be appreciated, thanks!
The down side of running out of gas is that all the crud in the tank is now at the mouth of the pick up tube in the tank. The chances of some of this stuff getting past the filters is high simply because there is so much of it and the forces pulling and pushing through the system are high. It's probable that something has ended up in the carb's idle curcuit.
