Tunnel Ram setup for the street

[volquartsen]

Hello everyone, new guy hear...Looking to build a street motor with a dual tunnel ram..Basically what I have now is just a 350 block with 186 heads..My build is a Chevy Vega with mostly 70's correct parts(Motion Build)..
I really want to run a tunnel ram this will be strictly a street car...

So here are some of my questions, looking for some suggestions on what tunnel ram to use, carbs, and any other
components such as cam, and compression to make this work on the street...

From what I have read Holley 390cfm carps work the best for this setup..Great but cannot find any 390 carps from the 70's that will not break the bank..Found some on CL but not really sure what I'm looking for, are all the 390 carbs setup for running on a tunnel ram setup? Guess I'm kinda lost here..Any help or correct part numbers would be great...Thanks in advance...
