That vin shows to be a 55 V8 engine built in Tonawanda that came in a 3100. https://www.gm.com/content/dam/compa...2nd-Series.pdf

Does it have a 55 265 in it or a V8? T55X is a 55 3100 with a V8.

If it has the 55 265 and the engine serial number matches you can figure that some time or other someone had the title changed to reflect an engine change. The engine change desination may have been lost over the years due to the DMV not placing it on the new title.

If it doesn't have an engine serial number that matches the title I'd be a bit suspect of it. If the engine blockserial number matches you are probably OK and can keep that block for show and tell if you do an engine swap.

I've got a very weathed 50 3100 door post tag still attached to a door post if you were to decide you might need it. No title with it as it came off a hulk I cut up 35 years ago.
