Proposed a filter, carb setup

Probably not what you want to hear, but I would look for a spreadbore intake. You haven’t even addressed the throttle cable issues yet from raising the carb over an inch+ whatever the intake adds. I ran a stock 340 un-silenced air cleaner with a RPM air gap. Needed a dropped base and and it still touched the hood. Had to extend the throttle cable bracket. You very quickly run out of room.
