I know a lot of people have had good results using the 600 CFM Edelbrock carb on normally-aspirated 289s, although a 500 CFM is plenty adequate, and that's what I run in my GT, and I'm happy with it.
Now I'm in the process of acquiring an R2 Avanti, minus supercharger and bonnet, but the rest of the R2 stuff is there. I have a Paxton on the shelf.
I'm trying to decide between using 500 CFM or 600 CFM Edelbrock carbs. The latter are currently on sale in Edmonton at an attractive price. Whichever carb I use, it will go in an R3-style pressure box, or some facsimile thereof. I don't want to mess with a "sealed: carb. If I can get a deal on a Lionel Stone repop pressure box, I'll use it, otherwise I'll go into full CASO mode. My objective is a nice driver, not a full-on R3 clone.
What's the consensus here regarding the carb choice?
