holley 650dbl pumper 4150 making noise.
ok when i start up my car its sound like it has a supercharger under the hood and the noise is coming from the carb, P/O had the same problem when he got the car and had rebuilt it and still dose the same thing, its coming from the primarys cause when u pull back on the throttle just a bit u hear it get louder. has any one had this problem before. and the motor is a 383 sbc.
