Otto, To identify which block you have: The S1 blocks have the oil galley drilled thru the lifter bores. S2 blocks had the oil galleys drilled just outboard of the lifter bores.

As previously stated, both the S1 and S2 blocks were made from the same raw casting, just machined differently. What size is your bore? I have a nice set of dished diamond pistons for a 3.800 bore I'll let go cheap.

the lifter bore are definetly machined on the outside of the block not thru the center. It is a 3.8 bore, How much for the pistons? and is the pin location for a 3.625 crank?
THanks Otto
