Engine Performance problem
1967 Other Pontiac Models V8 Two Wheel Drive Automatic 2000 miles

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.

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