Holly has a throttle body system good for 900 cfm. It sits where your carb used to be.
Is that big enough?

The 428 and 390 are physically the same, as are all the engines in the FE family. These engines were phased out around 1976, long before the days of fuel injection on standard American cars. The system on the 427 on Ebay is a Hilbourne system that is really meant for competition rather than daily driving. The aftermarket throttle body system that was mentioned is your best bet if you have to have injection. I have seen some custom multi-port systems for FE's but they are big bucks. I'll stick with my Holley.
