yo,
For Ford recommended gap see your Vehicle Emission Control Information (VECI) Decal; Contains Vacuum Diagram & Calibration Parts List for 88 & UP. On-Line for Free at Ford. Click "Quick Guides" in left panel; Scroll to & CLICK VECI Labels "Provides Vehicle Emission Control Information (VECI) and a related calibration parts list." Enter applicable info (need to know your Calibration number from your B-pillar sticker). Vacuum Diagram is the same as the one on the core support or hood or air filter cover. Suggest Right Clicking this Hot Link & Open in New Window

Typically, Ford shows Plug is AWSF-32C & Gap Shown is .042-046

Sixlitre Tune-Up Info (scroll through pages to view more tips, especially on Page 5); "...Yes, stock timing is 10 degrees, I find optimum timing to be almost exactly 13.5 but you can play around until you notice ping and then back off 2 degrees if you want to, and/or tune by vacuum if you care to. Cheapest Autolites money can buy, nuthin' platinum, nuthin' fancy, just set out to .055 gap..."; miesk5 Note, Vac Cannister info is for vacuum advance distributors by Sixlitre (Malcolm H, Eddie Bauer) at http://www.fullsizebronco.com/forum/showthread.php?t=63592&highlight=Sixlitre+tuneup&page=3

I didn't know if it was a stocker with a stock type ignition system or a wild pro built motor, I would go with the stock gap setting if it is all stock or close to it-
