Serial numbers on engine tell year?

[thomasat]

I am going to look at a motor and transmission Friday night. The guy on the phone knew nothing of the motor. The add actually read "nissian engine dual carburator transmission". So I belive him when he says that he knows little. I was looking in my Haynes and Chilton manuals, but they only show the info that I am able to get is size. I know I should know the diffrence between the carburators, from 70 - 73 but I'm still a little foggy. If any of you could help me out with a number range for each year if possible that would be great. I'll be sure to take some pictures to post to get the throbbing brain's opionon on the matter. Thanks

AFAIK, there is no published list of engine serial numbers. My brain recalls reading somewhere that the engines were mfg'd in sequence, but then diverted to various model assembly as needed. In other words. one engine sn# sequence used for ALL variations of Z manufacture for sale around the world. HS30, HLS30, etc.

Your best bet is to get the SN# of the engine and then look at www.Zhome.com in their registry of Z's. People have listed the VIN # and Engine # of their cars along with date of Mfg data. That should give you an idea of when the engine was manufactured.

It will only give you a rough idea. I have a serial number on the bodywork that has a higher no than a friends car, but he has a higher engine number than me.
