Engine number starting with AR, what is it???

I have a good single port engine that has a twin relief case and an engine number that starts with AR, any ideas what year/model it came from????

It also has the late model sensor it the case that is located at the back facing the flywheel.

Is it an industrial engine or just a late model 1600 with single port heads?

Any ideas?

Cheers

AR are the 73 on 1300 twinport engines from the 1300 pov beetles
the sensor the tdc sensor for the diagnosis plug
so yea its prbably just got 1500 heads on

So a good basis to use for a performance motor 😉

well aparently theyre a good bottom end to use as the lower compression and smaller capacity means theyre a less stressed engine
