More distributor/advance questions

As mentioned.....What are you starting with ?
You need to install this distributor,set the initial,and find out when it is all in.
On a DD/Street car, 12-14 initial 32-34 all in (2200-2500) should be adequate.
Remember, this isn't a clapped out drag car,so tune it accordingly.
After you get your initial timing set,then you can play with the vacuum advance.
