I think you could take a pair of 500 - 600 cfm carb (easy to find) and make a restrictor plate the same size as a 400 - 480 carb. Thin stainless with 2 gaskets might work. They do it in NASCAR. You need to reduce the air intake to keep the air fuel ratio correct. If you just jet the carb down you will end up with a lean condition. You must decrease the air and fuel together.

I know people will argue with me, and I'm not going to get into a pi$$ing match, but you need more CFM with dual fours. You do not want two 400 CFM carb's to replace a single 800.
