Which Carb????

I can get a Edelbrock thunder AVS 650 for $375 or a Holley street avenger 650 with dual fuel line and mopar adapter about $408. I have to get a carb before next Sunday's Albion,Pa Mopar Club show. Would have liked to get a Demon Speed 650 but by the time I add all the accessories I am put to $650. Please help. Summit can ship today a AVS or Avenger.
