Edelbrock carbs and open/single plane Torker-intakes don't always like to play well together.

Try installing a 1", or better, a 2" spacer under the carb and see how the engine likes that. (But make sure the spacer has 4 holes, not the 'open' type.)

The spacer mostlikely will improve the engine's vacuum-'signal' to the carb and it in turn, will react much better and quicker to changes in the throttle.
