There is no way to tell based on the stamp on the block. If you have the VIN number from a front clip you can tell that way. The 97-98 has a newer AC unit and alternator, S14 style TPS, S14 speed sensor in the transmission, uses the J4 ECU and has a different wiring harness. If you pull out a coil pack there should be a stamp that was put on it in the factory showing when the coil left the factory thus giving you a general idea of the age of the engine.
