Good carb to use with 318?

I'd look for a 600 Eddy. I have a 600 Carter, same thing, on my 273 an it works nice. A little more responsive down low than the 600 Holley I had on it. But both worked well. And with proper tuning will get decent mileage. I got about 20 with the Holley and highway gears. Not sure about the Carter, I put it on in the fall and swapped to 3.55's. Mileage went down, but it seems a little rich in the cruise mode. Some more tuning and some higher gearing she should be better than the Holley. But for now I like the 3.55's and the smoothness of the Carter/Edelbrock design.

I got my Carter on craigslist for 50 bucks and it just needed a cleaning, and some choke tuning.
