is it OBDI or OBDII

I think I have a 1995 LT1, I know the engine is out of a caprice. Can I ID it with any numbers off the comp or something? THing is I heard the 95's had 2 oxy sensors, mine I think had 4. this is throwing me off.

I would assume they went to OBDII something like half way through the model year.

Any thing I can check to tell?

thanks

P/S, I ran the vin, it came up as a 95, if it was the product of a mid year model change, would the vin reflect that?

If it was the product of a mid year model change, would the vin register as a 96 then, because mine came up as a 95.
