360 number stamp

[Johnny71dusty]

Did any of the 360/ start with a letter ? We really believe ours starts with the letter D but hard tell it's not a 0 and not a B or a 8

What vehicle is it out of and is it the original motor?

What is the concern if it does or doesn't?

No expert, but I think that looks like a five when I zoom in. Later 360 casting.
I never seen the casting number start with a letter yet.
