Need carburetor suggestions for 283ci

[chefk85]

I have been fighting issues with a 1977 qjet for months now. every mechanic I take it to adjusts it or rebuilds it and tells me its as good as it can get. I'm finally to the point I believe them. What would be the definitive answer be when it comes to this problem? I am in the market for a new carb but am having trouble figuring out what to get. Id hate to order one only to find its the wrong one for this engine. I would like to keep it original with a Rochester product. Any experts on carb setups for this engine? Its a stock 1967 283ci with headers, turbo350. Help!
