Block casting date.

This block/engine came out of a 68 satellite. since I can barely make out what it says,
Is there a date here when it was machined?

There is not a stamp pad on the oil pan rail for a vin number like all 68 and earlier blocks, but also the sequence number is not stamped into the bell housing rail.

All other internals would match a 68 engine though, forged crankshaft rod journals not cross drilled and the lighter 273 rods.

2197= August 3rd 1967

looks like 06 2 67 to me, so 413's machined date of Aug 3 is perfectly reasonable- and those dates make it a '68 model year block.
