    I have a nicely built 383 with 9.9 comp with the 3 separate pulleys I want to keep it looking stock so will this for under stock hood and is this a bolt and go or do you need extra parts?

    This is a complete kit by itself, so not many extra items will be necessary. This will fit under the hood of many full size GM vehicles.
