It will fit but you have to get a truck or Fbody pan, windage tray and pickup tube plus round up all the other missing parts. You're basically doing an OBS to LSx swap. You'll need a wiring harness, PCM, tune and all the other good stuff associated with a swap. Sounds like a great engine to start with. Does it have the accessories with it? You'll need an LSx starter to go with it, too.
