Both have their benefits, there are carbs on blow through pushing over 2000hp, fuel injection you can more fine tune per say but with fuel injection carb have also come a long way, I'd call or write a few company of both a see what they say, for carbs pro systems, c&s. Injection can write mega squirt. The 392 w albros are good pump I prefer bosch 044, found a site that sells cheaper but authentic, I bought two for my twin turbo dart on injection.
