You want to be careful, go slow, and read up a bit more. Too much advance, especially on boost or with poor fuel, can cause damage to your engine.

I'm not familiar with the 79, and I assume yours is ROW. Can you post what your owner's manual states for timing specs? That's a good place to start.

If you don't want to mess with locking down your distributor and your stock mechanisms are working, then you can save a few bucks with the standard 6AL unit. Or go with the -2 and program your curves at 0, allowing the stock advance (and retard if you have it) to do it's job. That way if you decide to go the programmable route, you already have the unit installed.

At a minimum, you need to get a timing light and verify that your advance/retard mechanisms are working properly and your static timing is set to spec.
