I have a 97 dodge ram van b2500 5.9l, i need help finding the engine serial number, ive already found the casting number

 

There isn't one. Why would you need it?

Welcome to DF!

 

The van wont turn over, ive changed all other possible parts that could cause no spark other than the pcm, so I ordered a pcm and they cannot program it without knowing if an engine swap has been done. The reason they asked is because the part number on the pcm came back as a dodge Dakota not a b2500 ram van, i just got the van a few years ago at 297,000 miles so I don't know all that has been done, how could i tell if the engine has been swapped

 

Look on the side of the block the displacement(318-360) will be cast into. You can also look up the casting #. If you are getting another pcm find the correct oem # on it. You can look at what it was used for with it.

 

Yeah, the PCM only really cares about the engine displacement. I.E. You don't really want programming for a 360, if you actually have a 318.....

 

Thank you guys sooo much i really appreciate the help, so all i need to tell them is that it's a 360 engine?

I don't think the picture loaded but it says 360 after the other longer number

 

 

Did you just give them that number for the pcm? I am needing a pcm upgrade. I have a 98 that had a 5.2 and now has a 01 5.9 but can’t seem to find the serial number just casting numbers

 

Because there is no serial number on the engine. The pic above shows a PART number, and displacement.

You don't need to replace your PCM, you need to get it flashed for the larger engine. Dealer should be able to do it, or, buy a tuner from one of the assorted companies that offer them.
