Which Carb??

Hello Out There!!

Need some advice.

Which Eddy Carb should I use on a mild 360 . auto. ?
I want to try the Eddy carb as I currently have a Holley Street Avenger .

Is a 600 enough and is worth to go to the Thunder series which the adjustable secondary or just use a straight Performer version only.

THanks in Advance!
