Hi,
I have a 67 Firebird with a 1973 - 400ci engine with HEI added along with a slight cam when it was rebuilt and automatic transmission. I bought the car this way and don't have any other details about the motor. It has a Holley 650 double pumper with no choke hooked up. I have to stay with a Holley or Quadrajet for the Ram Air kit to work. The carb sits on an older Edelbrock Performer aluminum manifold. I don't want to lose any performance especially take off but I think the carb needs replaced or worked on. The choke isn't hooked up but the car starts pretty good anyway. It will only be driven summers to shows and trips and that seems to be a problem with Holleys, letting them sit. Any suggestions? I was told locally the Quadrajet will perform as good or better than my Holley, what do you think? I want an electric choke and if a Quad is the best one how about a part number. One company told me to go with a M4ME but they come in all different CFMs. I have heard the term Quadrajunk and wonder!!! Any advice and help would be greatly appreciated.
