    While you have a gun you might want to find your optimum timing point. Mine is at 4 degrees but it's not stock. Each motor will run better at a certain point. Factory specs are good to have but i bet you will pick up a couple more if you run it a little closer to 0. Just make sure it doesn't want to knock.

    I am at 8000 ft and all my rigs are dialed up to 20 before. If I go down to the lowlands, I just dial it back down.

    I have been told start with factory then add 1 degree for every 2000 feet in elevation. anybody else heard that. When I lived near the springs I was around 12 degrees.

    That's a new one on me. I know when your lean detonation occurs with less advance. I always time for total timing (34-36 degrees) and try to get it in by 2800-3000 rpms. I usually run the vacuum advance off of "non-ported" vacuum.
