Mystery PCM

[lkurek at smtpgate.anl.gov]

     Well, the iron heads tell me it was NOT an F-body/Corvette motor, they 
     ALL had aluminum heads. The removable EPROM module then tells me it is 
     a 93 unit, since in 94 they went to the EEPROM OBDII ECMS's. However, 
     I don't think there were any cars in 93 that used an LT1 engine, other 
     than the F/Y bodies. If there were, they would be Roadmasters, 
     Caprice's, Fleetwoods (B Bodies I think). This is definately true for 
     94+, but I don't know about before that.
     
     So...assuming the stuffed LT1 engines into B-bodies in 93, THAT is 
     what I would say the engine came out of. It may be a 93 F/Y body 
     engine that someone put iron heads on...maybe they swapped them for 
     their Impala?
     
     TTYL!

     PS: Post the ID number from the block (front pass side...in front of 
     head) and that will tell you what year it is. Oh, does it have an 
     engine driven fan on it? The B-bodies had them for the HD cooling 
     option.

Everyone I am trying to identify the PCM and subsequently year and model for 
the engine that I bought.  After a conversation with fellow lister Ken, he 
suggested that I post the available information to the list and see if 
anyone out there can identify it.
     
The engine was sold to me as:  '95 Camaro LT-1 with 7,000 miles.  Iron 
heads, nifty looking intake manifold and all electronics.  Supposedly an 
emissions test vehicle motor
     
The PCM does have four big yellow male connectors on it, but it also has a 
removable EPROM module in it.  Which as I understand it should not be.
     
So here is the info from the PCM:
                > Here is the info off of my ECU.

                (checkmark) EFCB
     
     
So all this makes me wonder.  Anyone out there care to help me identify this 
engine and PCM combo?  I am looking for the serial number from the top of 
the intake manifold as we speak.
