"This was an intense install i would not recommend potential buyer to do it yourself unless you know what you are doing and have 2-3 hours to burn. It works fine with my Poweraid throttle body spacer, however i did have to find longer bolt to make both the space and the BBK 80MM throttle body space work. Not sure about fan shroud clearnce for the factory mechanical fan unit because i have a felx-a-lite fan unit installed on my ride it frees up a lot of space under the hood." —Jason W from Chesapeake, VA bought a BBK Power-Plus Throttle Bodies for a 2004 Chevy Silverado, 5.3L V8.
