If you buy a drop-in GM crate engine, nothing would be needed to complete the ENGINE; it's as complete as you can get.

What you will need is the proper hardware to install the engine as well as vehicle-specific LS headers if you decide to go that route.

Best of luck!

I have the 376/480 in my car. Ended up camming it with a Brian Tooley Stage IV and it made 481 with supporting mods. Runs great without any issues. Needed some conversion stuff though.
