Carb for a 340?

yeah, im torn on the Eddie/Holley thing. Had both, had problems with both..the Holley always started ok but had a bog/stumble that we could not get rid of(even took it to a shop that restores old cars and had them take a try at it and it seemed ok for about a month then not so good it was a Holley 600) and the Eddie runs fine when running no bogs or stumbles and good throttle response...but leave it sit for a week or more and its like its been sitting a year its that much of a PITA to start. Never actually had a carb yet that actually just WORKED...as in started easily even after sitting a week or 2, and ran right lol.
