This info is the calibration sticker for your engine.
Your engine calibration number is :
7-60-R16
Go to my web site and find the calibration coding & specs links at the bottom of the Index page.
8 bolts on the valve cover is either a 351M or 400.
385 series engines have 7 valve cover bolts.

Calibration codes starting with 7-60 are a 351M. It also appears to be for an F100 w/ automatic.

It means your valve covers are from a 351M - perhaps they are original with the truck. In 25 years, a lot could have happened to the long block. Someone could have swapped in a 400 from a car - and moved a bunch of the original parts over.
