I have a tall deck 427 with an 871 supercharger on it. It has been all done up.I was wondering the factor timing is 4-6 degrees and I was wondering in a blower app. If I can advance the timing to to 18 degrees.

Do you
have the same problem?

You probably can, you'll just have to watch for spark knock and leaning out. You'll also have to watch for pre ignition.
