If you're going to swap to EFI now is the time to do it- it'll never be cheaper or easier. Even if you can't afford a good multipoint system a junkyard TBI unit on top of your carb manifold is a great way to get started. That way you'll have your EFI fuel system already in place should you decide to upgrade to multipoint down the road.
FWIW you can convert to TBI for less than the cost of a new carb. You can also swap in a JY distributor allowing computer controlled timing advance. 400hp will be maxxing out stock BBC TBI injectors though, the BBC throttle body itself will flow more than enough air with a little finessing.
