Hi new member here and first post. Can anyone identify the day and year of my 340 engine in 71 Demon?

Stamped below drivers side head is, FW340P32610515.

Thanks

Looks like a 70 model not sure how the rest shakes out, some thing about shift date etc...

Thank you, I knew everything but the 3261. Didn't know how that converted to a date.

There should be a partial VIN stamped on the passenger's side pad. That will help identify what it came out of.

F - Series (model year) 1970
W - Windsor Ontario plant
340 - 340 CID
P - Premium fuel recommended
3261 - Engine final assembly date from the 10,00 day calendar July 2nd 1970
0515 - 515th engine assembled at the plant above on the day above.

The partial VIN may provide a clue about what type of car it came from.
