Super six timing

Just pulled two different ones apart. One electronic and one points.....both had 15L advance plates in them....that equals 30* advance. On a slant your would have to run it at 2 ATDC to be in the best range and a small block you couldn't set initial much more than 4*. Why do they all seem to be like that? Where are all the 9R advance plates?
I have no idea
If you look at the FSM for slant6 cars all through the years they all say to set timing around 0 degrees. Check it out.
I even had a reputable member of the .org forum recurve me a distributor and it still pinged because he didn't weld the advance plates. You HAVE to weld the advance plates (or solder, or JB weld if it lasts, etc) the advance plates on all OEM or rebuilt/remanufactured slant6 distributors. It sucks and it's a pain but it's ping ping ping unless you do it. Unless you want to run your car like a dog at 2 degrees or so advanced.

This should be a sticky in all slant6 forums because it's such a problem with today's gas that people aren't informed of
