92 LT1 OBD1 change to OBD2 is recommendable?
Will the installation of an OBD2 on my 92 Corvette give any benefit?
If so, what year OBD2 will fit?
Is this a simple remove and install change?
Suggestions please

No.
The 94+ PCM's have completely different connectors , would require a later model engine harness or some serious cut and splice work
If you were really wanting to do anything you would stay OBDI and swap to the common 94/95 LT1 PCM to get a way from the problematic 92/93 ECM you have
Many OBDII owners convert back to OBDI if only for the cheaper tuning software and less sensors

I don't know of a "problem" with the 92/93 Y body or 93 F body pcms (same part by the way but different chip) other than they use a reprogrammable chip which requires both a chip burner and chip eraser, but once that is done you are good to go. 27C256 chips are about $15 for 10 on ebay.

Do a search.
Many have had non memcal related problems with the early LT1 # 16159278 /88999183 ECM ;loss of serial data (DTC 41 ) appears to be a reoccurring problem
The ECM long time unavailable new or rebuilt from GM http://www.gmpartsdirect.com/results...umber=88999183
and subject to some " marginal" rebuilds ( the only replacement option ) if posts on here are anything to go by.
