" this carb is ready to go out of the box. i was a little leary about the install but the directions are clear and process was smooth. without any mods or adjustments to it i put it on a highly built up fresh 327. once the bowls filled it took a few pumps of the pedal and that was it. if you are thinking about the truck avenger, pull the trigger on it. you will be very happy. "
Pros: installation, good instruction
Cons: none so far
