Default 408 intake & fuel injection options

I just had a 408 built with cnc'd ls3 heads. I need some options on the best intake and fuel injection setup. Would it be better to run a factory setup and computer or go with a aftermarket setup? I have not bought anything yet so I could go either way. Also this is strictly a race engine that will be in a tube chassis so the fewer amount of wires the better for a cleaner look. thanks in advance

High revving screams single plane to me Victor Jr probably be the best for the cam you have

ProFlo is probably better than a carb style intake if you have the room, or really if lots of revs a HiRam

As for computer, largely it will depend on who's tuning it.

For an easy install and complete loom with almost zero DIY effort, maybe this ?
