If you don't have a timing gun ( pulsing light), or don't know how to use one, then don't. Get a shop to do it. If your timing is even a little bit off, it can destroy the engine. I watched my friends GTO 's engine die a very loud and surprisingly violent death. If you really want to do it yourself, make sure you understand everything in detail before you even start, and maybe practice on someone else s car. Just kidding,,,, Good luck. Grimm
