Someone please help me find out what kind of block this is. I looked for the casting numbers near the starter and all I could find was this:

5 (big)
FISE
BB

then near where the bell housing lip on the block is:

4D2

I can find no other casting ID's on the block except two circles with numbers in it.

Thanks

F1SE would be a 1991 thunderbird engine, more that likely a 5.0, and a single B means first revision, but two of them arnt uncommon. The 4d2 doesnt make too much sence because the only thing it fits a date code which would be april 2nd, 1994.
