What will the 440 put out as far as HP?
What is your intended cam specs and gear ratio?

Older 440 cars came with small AFB carbs, (600 CFM) coupled with Hwy. gears. An old friends Imperial comes to mind. IIRC, it was a '67. Just talking out loud here. If your car is equipped with extra performance parts, that 3310 suggestion is a good idea.
