Upside down 352 on FE block
I've got what appears to be a 1975 FE390 block that came out of a truck. The strange thing is on the left/front of the block, under the head, the "352" is cast upside down. Directly above the upside down casting is a larger "6" (or 9 if its upside down too). I've never seen the 352 cast upside down before, anybody else?

Upside down 352 on FE block
I have it on my 390 as well.
My auto shop teacher back in high school told me all FE blocks had that stamped in them... at least his 428 and all the other FE's he had seen had it.

All FE engines, 390,360,428,etc. are derived from the 352 FE engine.All of these engines used the 352 block, according to the "Rebuilding Ford FE books", because the 352 had so much girth to them, they could be bored out to provide the necessary cubic inches.

Not ALL FE's had 352 on the block. Some heavy duty blocks had an upside down and backwards 105.

Proeliator, people seem to have missed the point of your post - yes many FEs have "352" cast in front of number 5 cylinder, but I have never seen or heard of one where it is upside down. I checked what books I have and many had pictures of the normal "352" none mentioned an upside down one.
I hope somebody can explain this to us.
