Can I use stock gages with LS1?

[Project Cortez]

Getting ready to drop my LS1 engine into my 69 camaro for fitting etc.... Want to know if I can still use the center console gages (Fuel,temp Etc...)? Im pretty sure I can reuse the stock speedo and tach. Just heard rumors of not being able to use the console gages. Want the car to look all stock. Thanks for the help
