I reread Santucci's chapter on ignition, it's a short one. He was recommending for "street/mild strip" 10* initial advance with full advance at 3k rpm, and total timing at 32*-38*. He also suggests widening spark plug gap to between 0.050" and 0.080". I'd like to achieve maximum mpg in this stock configuration, so I wonder how much I should deviate from the factory recommendations?
