You will also need LS adapter plates and there are some decisions to be made because there are some issues involved with leaving the A/C compressor in the stock location.
If you leave the A/C compressor in the stock location you will have to make custom adapter plates, trim your frame and have custom hard lines made for the compressor.
The best option is to buy a A/C compressor relocation kit and move it to the top passenger side of the engine because it makes it easy and easy is good because it requires no custom made parts, Holley sells an inexpensive kit, and don't balk at the price because you will spend that much anyway with all the custom work if you have to pay someone to do it.
