I would personally go with an efi setup. I went with a very radical cam on my ZZ4 setup with some big heads for supercharging in the future. My FiTech can keep the motor running at 500 rpm although I run it about 700-800. With my cam that would be difficult with a carb. Really shows how amazing fuel injection is. You could go with a bigger cam and the efi will keep it streetable and running nicely at idle. You might even tap into some power that you couldn’t get out of a carb with more accurate tuning and better atomization. Combine that with better fuel economy, the ability to have a perfectly tuned car if you decide to take a road trip through deferent altitudes, and the affordability of Fitech it’s hard to go wrong. I bought my unit 2 years ago and love it, my dad then bought one and loves it, my buddy then bought one as well for his Nova and he loves it.
