Right now I am running a stock, tired 250 with a Clifford 4v intake and various 4v carbs (Holley and Autolite). The mismatched engine feels like a sick dog until about 3500 and then it feels like you flipped the "NOSS" button.
Sounds like you have the Clifford intake no low end Blues.
Have you tried a Offy intake?
When you run the Offy intake, the carbs will get a much stronger signal also.
