Not really, other than it will be on the large side. I think the injectors are rated to 300 hp.
It would be nice if they made a 350-400 CFM unit.
Holley offers the following Throttle Body Fuel Injection Systems:
Commander 950-19S....400 CFM....225 HP
Commander 950-20S....670 CFM....275 HP (Recommended for engines over 200 hp)
