Use a victor efi with an edlebrock 90 degree throttle body adapter and an ls 90mm throttle body. Almost all aftermarket efi systems are set up for the gm sensors already and it makes it super easy.
I endorse this picture lol it does clear a factory hood too, I added the scoop just to have some cold air blowing on the inlet to help keep the air charge colder. Here's a different pic without all the wires and piping.
