I have a 59 364 with a four barrel square bore factory. I want to get this motor running so I can sell it. I have everything I need with the exception of a carburetor. This motor is set up for a manual transmission in a traditional hot rod so I don't need one with automatic transmission linkage. I have an Edelbrock 600 CFM that I can rebuild. 600 cfm works great on a 350 Chevy but I have been told (here) that Nailheads run better if they are over carbureted. Should I look for a 650 or 700. What is best. I like Edelbrock carbs but I am not locked into any particular manufacture.
