I have a block and am trying to find some info about it. On the back of the there is a 6 digit number that reads 010207 just like that and on the front pad on the right side is V0305FSD and the number below that is TES520501. I know the last number probably a partial VIN but I can't figure out the engine suffix code of FSD Help is greatly needed. Thanks Darrin

That's a strange one!

FSD = Farm Service Duty???

Wonder if it was an industrial replacement or something else...

is there a block casting number? It is usually 7 digits and is located on the back of the block down toward where the bell housing bolts up.

The block casting number thats on the back is that 101207 no other number or stamps other than a date clock. I even checked down near the oil filter location. It also says CFD207 on either side of the block and passenger side dip stick. As for double stamp its a clear FSD.

sorry I can't help with that one, I have never seen any codes or casting number like that.
