Annular Boosters for Edelbrock carbs?

Does anyone make/sell annular boosters for edelbrock/carter style carbs? Thanks

Probally not, have you looked at the rear fuel feed devises on the AVS style carbs, same as the Thermoquads Are you aware that most of the 4150 Holley carbs with annular booster, go fatter the higher you rev the motor Another thing to keep in mind is that the skirts on the annular boosters limit the airflow to less than with conventional boosters in the same carb
