This is not a good idea at all. Most of the time one tooth can be 8 degrees or more and can mean the difference between the engine running at all or not. And then theres the interference part of it.
This is why theres adjustable cam gears. Not sure if the Atlas has a big aftermarket or not. Even then theres the VVT to deal with. In this case some sort of tuner would probably take the role of the cam gears.

To advance ignition timing, first make a line on your distributor and motor at the stock setting (often 16°) and the turn the distributor slightly. The direction that makes idle go up is advancing.
If you have a timing light, the flywheel has markings for stock, -2° and +2° usually.

Sorry, but an extremely moot post. Im not sure if distributors were even used this century. Ignition timing is completely controlled by the ECU.

I would be afraid of the main bearings being beat to bits lugging that low. I could be wrong though.
