Help decoding engine casting numbers
 

Can someone please help, I need to find out information on this motor that I have.

Here are the numbers:


FO4i2C (stamped in the passenger side front of block)

3756519 (this is on the drivers side rear of the engine)

D11 (back side of the block-passenger side)

H-8 (passenger side rear)

870 (passenger side rear)



Any help would be greatly appreciated!
Thanks
