I just what to add that these concepts apply to most other distributors. Changing the degrees of advance in different brands varies on how that is accomplished. Some are easy to change, others are not so. Before you buy a distributor get the tech information on that distributor and find out what advance is built into the distributor and is it easily adjustable. Plus, does it come with various advance springs to change the rate of the advance. It is very important that you know what is built into the dist. so you know where the timing should be.

Since these cars are very hard to hear if they are pinging, it is more important that you get the timing in the ballpark or you can cause a lot of damage to the engine. In my opinion if you buy a distributor and just set the initial timing at idle without knowing what's in the distributor you could be making a big mistake. There are a lot of pretty billet distributors out there, but what's in it. Is it what you need for your engine, and the most important factor other that what engine, is what duration of cam you have in that engine. There are several other factors I mentioned earlier. Because of these variables of each engine a distributor you buy needs to be adjustable. Think about it.
