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?

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.

Maybe they use the 352 cast for making all the blocks?

Upside down 352 on FE block

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.

My "63" 406 does not have the 352 cast there so i'd say not all FE blocks have it. I've also seen the 352 both ways on different blocks. G.

There you go - I am not sure anyone has claimed the "352" is on all blocks, but in any case FFR428 has seen the "352" upside down.

I've seen a mirror imaged 352. Is that what you mean by upside down 352?
