E85 or race gas? Uncorrected or corrected?
2G DSM I assume based on your profile?
I'd say you'll need FIC 1680's or the 2150's.
You will definitely need either a BAP on your 255 and maybe a second pump or a bigger base pump (like the Walbro 400). This is where you get to spend a lot of time researching other people's setups and then decide what you want to do, then spend money and more time making it work.
