87 Integra(Browntop) ZC or D16A1???

[speedyed]

Hello I'm new to this group and I was wondering if someone can help me with this problem. 4 years ago I had my stock motor replaced by a japanese replacement motor, a brown top ZC. This motor came with Carburators and had several Honda metal paques all in japanese. I'm desperately trying to find out where I can find out for SURE if it's a ZC by finding the darn ZC stamp. My understanding is that 88-89 ZC (BlackTops) have the stamp in the front but what about the 86-87 Brown Top ZC's?? If anyone can help I would really appreciated.

Look on the rear of the engine just to the left of where the tranny bolts to the block. Should be just above the rear engine mount. You may have to clean the area of to see it.
