Life after Holley Sniper - back to Carb

After a couple of years with the Holley Sniper EFI and it’s problems I now decided to go back to carb.
I need some suggestions, so I buy one I can work with.
I tried Edelbrock 1405 and 1406 before the Sniper, was never happy with.

318 with 904.
Edelbrock RPM Airgap intake
Edelbrock RPM Aluminium heads
Zero deck (10.5:1)
I beam rods + KB Pistons
Lunati Cam 10200702

Thanks!
I have had a 650 Mighty Demon on my 71 340. Fantastic, problem free
