Gen3 to Gen4 install 1. Make sure your knock sensors are the same size threads if not have them tapped to match your current sensors.
2. If your going to use your stock oil pan sent it to your builder and let him space and clear the windage tray oil pan and pickup tube and even tap the knock sensor holes if needed
3. make sure you have all the wiring adapters you will need
4. a little grinding on the motor mount may be required
5. If you dont already have a keyed harmonic balancer you will need one as L/92 LS3 are keyed
6. if you have a 2 line fuel rail you will need a 1999 filter regulator for the new single line fuel rail. I put mine were the stock filter was.My psi at the fuel rail is 58 and @ WOT I have 58-61 psi
7. My LS1 valve covers did not clear the valves so I used the GM performance ones
Good Luck,
rookie
