I had the same question I asked one of the guy's on here and they told me that the date on the block is under the oil filter mount on the small angle ridge I got a 390 two and my date is under there, if I am right all the FE,s is there.If you can,t see it real good, use playdough on it and it should come out pretty good.It should look like someting like this 9A02. 9 for the year, A for the month, and 02 for the date.Dave
