    I would recommend a compression test first. Record and post the readings. Are you using the original stamped rocker arms?

    I will post compression test results. My friend has to come over with her compresssion tester.

    I used COMP Cams Pro Magnum Shaft Mount Roller Rocker Arms 1622-16

    Wow! Nice 340 build! These Edelbrock carbs are ok for a stock to mildly modified engines. Your 340 with 7-8 InHg at idle may be too much for this carburetor making it difficult to impossible to tune. Was the cam installed with a degree wheel or "straight up"?

    I agree the Eddy carbs are not tunable , change the carb tune it in& the problem will go away
     I like the proform carbs , best bang for the $$ spent
