Carb Choice (New 318)

There is endless debate on these forums about your question. My mildly modified 318 started with an Edelbrock 600. I could not get heat boiling issues to resolve despite trying multiple different things. I switched to a Holley 600 and have had absolutely no problems since. But opinions vary widely on this subject. Pick one, run it, and if you don't like it switch to the other option. I wouldn't go over 600 because there is no need to over-carb your car. 600 cfm is more than enough for a mild 318.
