Denny,
It looks like Plasti-Kote has two gray engine enamels which are "Universal Gray" and "New Ford Gray" as follows:
ENGINE ENAMEL
END ITEM CODE PART # DESCRIPTION UPC
400.0000202.076 202 Universal Gray 0-71915-00202-1
400.0000216.076 216 New Ford Gray 0-71915-00216-8
On the web site, they appear to be close in color to each other. Here is a link to the information page and color sample page (if they work).
