351C engine problems

It's very likely that the float level is wrong on a new carburetor. New never means it is working properly or adjusted correctly, on any car part.

Are you using an electric fuel pump? How is it wired if you are? How do you know the fuel pressure drops? if you have a gauge mounted is it electric?

The more I think about it the more I suspect something simple, like an electrical issue.

+1 to this. Never assume it's not your new parts.....

the new carb may need a metering rod or jet change to richen up idle. any surging on freeway? stumble flat spot during accell?

I've had a few new Edelbrocks, and I remember just one of them that didn't need adjusting out of the box.
