i bought a used hd motor and i was told by the guy that it was a 1340. the trans is connected to the case and it is apparently an old motor. i have surfed numerous sited and have not found how to decode the vin number that i found on the left side to the case. please help!!!! the vin code reads as follows.....(star DJLH500573 star)&nbsp\\;\\\\\\; if anyone can help it would be much appreciated. thank you all for reading this.

 

Go on the MoCo website and call the customer service line. They will tell you.

 

&nbsp\\; From what I found, those numbers are not indicative of engine numbers for any of the 1950's - 2000 year models. Are you sure this is a Harley engine, or are there any more numbers that begin with a number instead of letters?

&nbsp\\; Do a search on Harley engine codes and see what I'm referring to. Most of the time the engine serial number is a shortened version of the main VIN that is on the frame.

 

&nbsp\\; Alright, I looked a bit harder and found another site that gives more insight to the code you gave. If I read it correctly, it looks like you have a 1987 1340" (EVO) engine. I'm not exactly sure as the whole article is long and detailed, but I'll give you the link and you can see for yourself.
