    Fuel system conversion advise

    Just bought my first square body. Its a 1976 C20 burb 454. Its a beautiful truck with extremely little body and frame rust. The previous owner did a tbi conversion. Long story short the truck does not like to idle, wants to bog down when given above 50% throttle, and seems to be running...
