I saw your build thread https://67-72chevytrucks.com/vboard/...=846353&page=5

You must be planning to put a carb on it as part of the 'looks like SBC' plan?

It sounds like you have a LS swap under your belt already. So you know they are pretty darn good. Personally I'd stick with stock LS intake and computer. And recommend HP tuners to anyone doing that. There is a pretty good community around it and everything you need to know to redo a factory harness or roll your own is out on the net for the taking. Or buy a harness.
It's probably easier to find someone that can sort out issues or put a tune on an LS than a carburetor these days.

someone should make a fake roots blower shell to cover a LS intake and coil packs
