To be period correct, you've got to run a pair of Holley carbs. Edlebrock's weren't around any any close equivalent is just lame IMHO.
This is the empitome of 1970's day 2 TR's. This is a Weiand, but I don't know the model. It has a pair of 450 carbs, but the ol' 1850 600 cfm are cheaper and easily tuned for this application. I run them on my 327 too.
There is something about the way this intake looks that I really dig more so than the Two Lane Blacktop set-up.
