If you use a "Hat" you will have to have a blow through carburetor.
The Edelbrock carbs are not one of my favorites, but it may be possible to modify it to work.
I would guess that you will need a fuel pump that will supply around 225 LPH at the pressures you specified.
You will be running lower fuel pressures, but you will need to supply sufficient fuel volume for your engine modifications.
