Need a new carb

Definetly go with the Edelbrock Air Gap intake!! It will be a huge improvement over the other intake you are running! I would go with a 650 cfm or a 750 cfm vac secondaries carb. On my 340 I have a Eddy air gap, 750 Holley, .509 Mopar cam, and a 3500 stall and it works great! I have 3.91 gears, with your stall you should go with 3.55 or 3.91's. :thumbup:
