Need a new carb, What CFM?

[javajesus]

The PO of my bought said that the carb was a marine carb. The mubers I found off it show that it is marine on google, but it has no J tubes and everything else looks like it is not marine. So, my question is, what CFM carb do I need for my 77 OMC stringer GM 350 V8? I would like to stay with the Holley 4bbl.

600 cfm is all you need, a chev 350 flows 600 cfm at 6000 rpm at 100% volumetric efficancy. the average motor is only 85% at best so a 500 cfm will work also but they are a little harder to find
