casting numbers... i searched
i cant find a 352 or a mirror 105 on my block at all, the only castings i have found are DIF 32 on the drivers side front. the heads are D2TE-AA i know those are standard 70s heads with hardend seats, the intake is C4SE9425A which is a standard 4bbl intake. the thing that has me stumped is the DIF 32, i know DIF is deerborn iron foundry, but what does the number mean?

Some blocks dont have either the 352 or the mirror 105. Those are usually FT blocks. The ones without anything there should have the same features as the mirror 105 blocks (extra main webbing, higher strength iron, thicker cylinder walls, etc.)
Go look again. It should be on the front of the block, driver side, right under the cylinder head.
As for the DIF32, I honestly dont know what the 32 means. But it's interesting, as I thought most of the heavy-duty blocks were cast at MCC.

i looked and felt all around under there, there is a raised area that is flat and about 1"x2" and is blank and then there is the DIF 32 all this is in the area you said, right under the head on the front. i know it is a 390 seein as i have the reciept from jasper. also on the passenger side there is nothing at all, i used a mirror and a flash light and went all along there under the manifold and not a single casting mark.

It could be a service block. But then even then the 428 ones I had all had the 352 and DIF markings. Are there vertical ribs on the sides of the block? What is the date code of the block? And see if there are two dots under the first number. Last do you remember seeing a triangle on the tops of the maincaps? Either way the date code can help explain it's timeframe.

The difference with the FT cranks is in the nose. That means the timing cover hole has to be bigger. They simply use an FE timing cover, and an FE crank.

just pulled C6ME-A from bout midway down the block in the front on the pass side, i have vertical ribs running from the top of all the freeze plug holes. the date code is behind the starter right? i also got under it and crawled around to get a better view and there is definately not a 352 or a 105 on it all i saw was DIF and 32. i havent been into the bottom end of the engine, i havent had a need to. it is still in the truck running fine i just got curious of what block i had.
about the crank and timing cover, see sometimes my brain decides to stop working on me

7E24 no dots.
May 24 1967?
i thought i read some where about it being behind the starter, and as soon as i got done dropping it i rememberd it was by the oil filter. the search wasnt working so i just went for it. now im off to go loose feeling in my fingers and put it back in.
edit: i found a picture of a service block and i dont have ribs running up the block like that.
